Pacifism

General Pacifism
Jesus states principles regarding treatment of one's enemies that are unparalleled, setting a very high standard for not just forgiving one's enemies, but proactively praying to God for them. Nor is this a standard to be taken lightly, for it is the requirement Jesus sets to be "the children of your Father in Heaven." As Jesus points out, if we only care about those who care about us or are related to us, we are doing nothing special and therefore cannot expect any reward. As Jesus further points out, we cannot expect to be forgiven for our sins if we do not forgive others. Nor is this a new commandment, but one that God gave back in Leviticus 19. Jesus similarly states that this should extend to generally taking wrong.

Luke 6:27 But I say unto you which hear, Love your enemies, do good to them which hate you, 28 Bless them that curse you, and pray for them which despitefully use you. 29 And unto him that smiteth thee on the one cheek offer also the other; and him that taketh away thy cloak forbid not to take thy coat also. 30 Give to every man that asketh of thee; and of him that taketh away thy goods ask them not again. 31 And as ye would that men should do to you, do ye also to them likewise. 32 For if ye love them which love you, what thank have ye? for sinners also love those that love them. 33 And if ye do good to them which do good to you, what thank have ye? for sinners also do even the same. 34 And if ye lend to them of whom ye hope to receive, what thank have ye? for sinners also lend to sinners, to receive as much again. 35 But love ye your enemies, and do good, and lend, hoping for nothing again; and your reward shall be great, and ye shall be the children of the Highest: for he is kind unto the unthankful and to the evil. 36 Be ye therefore merciful, as your Father also is merciful.

Matthew 5:38 Ye have heard that it hath been said, An eye for an eye, and a tooth for a tooth: 39 But I say unto you, That ye resist not evil: but whosoever shall smite thee on thy right cheek, turn to him the other also. 40 And if any man will sue thee at the law, and take away thy coat, let him have thy cloak also. 41 And whosoever shall compel thee to go a mile, go with him twain. 42 Give to him that asketh thee, and from him that would borrow of thee turn not thou away.Ye have heard that it hath been said, Thou shalt love thy neighbour, and hate thine enemy. 44 But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you; 45 That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust. 46 For if ye love them which love you, what reward have ye? do not even the publicans the same? 47 And if ye salute your brethren only, what do ye more than others? do not even the publicans so? 48 Be ye therefore perfect, even as your Father which is in heaven is perfect.

Mark 11:25 And when ye stand praying, forgive, if ye have ought against any: that your Father also which is in heaven may forgive you your trespasses. 26 But if ye do not forgive, neither will your Father which is in heaven forgive your trespasses.

Leviticus 19:18 Thou shalt not avenge, nor bear any grudge against the children of thy people, but thou shalt love thy neighbour as thyself: I am the Lord.

This principle is further echoed by Paul in his epistles:

1 Corinthians 6:7 Now therefore there is utterly a fault among you, because ye go to law one with another. Why do ye not rather take wrong? why do ye not rather suffer yourselves to be defrauded? 8 Nay, ye do wrong, and defraud, and that your brethren.

Eternal Reward
This seems to be related to the principle of God wanting us to take wrong while doing good, that we may have more eternal reward:

Matthew 5:10 Blessed are they which are persecuted for righteousness' sake: for theirs is the kingdom of heaven. 11 Blessed are ye, when men shall revile you, and persecute you, and shall say all manner of evil against you falsely, for my sake. 12 Rejoice, and be exceeding glad: for great is your reward in heaven: for so persecuted they the prophets which were before you.

Luke 6:21 Blessed are ye that hunger now: for ye shall be filled. Blessed are ye that weep now: for ye shall laugh. 22 Blessed are ye, when men shall hate you, and when they shall separate you from their company, and shall reproach you, and cast out your name as evil, for the Son of man's sake. 23 Rejoice ye in that day, and leap for joy: for, behold, your reward is great in heaven: for in the like manner did their fathers unto the prophets.

Luke 6:37 Judge not, and ye shall not be judged: condemn not, and ye shall not be condemned: forgive, and ye shall be forgiven: 38 Give, and it shall be given unto you; good measure, pressed down, and shaken together, and running over, shall men give into your bosom. For with the same measure that ye mete withal it shall be measured to you again.

Eternal Punishment
The Apostle Paul, in urging Christians to do good to their enemies, further reveals that doing good to one's enemies will ensure that, if they do not repent, they will have even greater punishment from God, in effect "heap[ing] coals of hot fire on their heads." (Romans 12:20)

Romans 12:17 Recompense to no man evil for evil. Provide things honest in the sight of all men. 18 If it be possible, as much as lieth in you, live peaceably with all men. 19 Dearly beloved, avenge not yourselves, but rather give place unto wrath: for it is written, Vengeance is mine; I will repay, saith the Lord. 20 Therefore if thine enemy hunger, feed him; if he thirst, give him drink: for in so doing thou shalt heap coals of fire on his head. 21 Be not overcome of evil, but overcome evil with good.

Christians who have died do so anticipating God's coming justice:

Revelation 6:10 And they cried with a loud voice, saying, How long, O Lord, holy and true, dost thou not judge and avenge our blood on them that dwell on the earth?

Revelation 13:10 He that leadeth into captivity shall go into captivity: he that killeth with the sword must be killed with the sword. Here is the patience and the faith of the saints.

Luke 18:1 And he spake a parable unto them to this end, that men ought always to pray, and not to faint; 2 Saying, There was in a city a judge, which feared not God, neither regarded man: 3 And there was a widow in that city; and she came unto him, saying, Avenge me of mine adversary. 4 And he would not for a while: but afterward he said within himself, Though I fear not God, nor regard man; 5 Yet because this widow troubleth me, I will avenge her, lest by her continual coming she weary me.6 And the Lord said, Hear what the unjust judge saith. 7 And shall not God avenge his own elect, which cry day and night unto him, though he bear long with them? 8 I tell you that he will avenge them speedily. Nevertheless when the Son of man cometh, shall he find faith on the earth?

Satan's Planet
Satan is the 'prince of this world' and 'god of this world' until he is finally deposed in the last days by God the Father. As such, avenging ourselves against the forces of darkness which rule this world, 'principalities and powers,' may be a losing battle.

Matthew 5:25 Agree with thine adversary quickly, whiles thou art in the way with him; lest at any time the adversary deliver thee to the judge, and the judge deliver thee to the officer, and thou be cast into prison. 26 Verily I say unto thee, Thou shalt by no means come out thence, till thou hast paid the uttermost farthing.

Luke 12:58 When thou goest with thine adversary to the magistrate, as thou art in the way, give diligence that thou mayest be delivered from him; lest he hale thee to the judge, and the judge deliver thee to the officer, and the officer cast thee into prison. 59 I tell thee, thou shalt not depart thence, till thou hast paid the very last mite.

It should be further observed that, since this is Satan's planet, those in power will be particularly biased towards those who do good. As such, every action must be thoroughly justifiable to all people, that Satan's ministers do not gain an excuse to persecute Christians.

Romans 12:17 Recompense to no man evil for evil. Provide things honest in the sight of all men.

Potential Exceptions
That there are exceptions is evident. Paul urges Christians to, "if it is possible, as much as lies in you, live peacefully with all people." (Romans 12:18) This passage thus shows that there will be cases where it is impossible, both given the circumstances and one's own nature, to live peacefully with others, even when committed to generally taking wrong and forgiving one's enemies.

Romans 12:17 Recompense to no man evil for evil. Provide things honest in the sight of all men. 18 If it be possible, as much as lieth in you, live peaceably with all men. 19 Dearly beloved, avenge not yourselves, but rather give place unto wrath: for it is written, Vengeance is mine; I will repay, saith the Lord. 20 Therefore if thine enemy hunger, feed him; if he thirst, give him drink: for in so doing thou shalt heap coals of fire on his head. 21 Be not overcome of evil, but overcome evil with good.

Even Jesus could not stand the sight of all evil, and intervened using physical force when He saw God's temple being misused for material gain through fraud and dishonesty.

Luke 19:45 And he went into the temple, and began to cast out them that sold therein, and them that bought; 46 Saying unto them, It is written, My house is the house of prayer: but ye have made it a den of thieves. 47 And he taught daily in the temple. But the chief priests and the scribes and the chief of the people sought to destroy him,

Mark 11:15 And they come to Jerusalem: and Jesus went into the temple, and began to cast out them that sold and bought in the temple, and overthrew the tables of the moneychangers, and the seats of them that sold doves; 16 And would not suffer that any man should carry any vessel through the temple. 17 And he taught, saying unto them, Is it not written, My house shall be called of all nations the house of prayer? but ye have made it a den of thieves.

Matthew 21:12 And Jesus went into the temple of God, and cast out all them that sold and bought in the temple, and overthrew the tables of the moneychangers, and the seats of them that sold doves, 13 And said unto them, It is written, My house shall be called the house of prayer; but ye have made it a den of thieves.

Declaration of Independence
This is, essentially, the same argument made in the Declaration of Independence for creation of the United States, that the colonies had repeatedly attempted to compromise and seek a peaceful resolution with England, but that evils had become finally insufferable.

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.--That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, --That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness.

Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security.--Such has been the patient sufferance of these Colonies; and such is now the necessity which constrains them to alter their former Systems of Government. The history of the present King of Great Britain is a history of repeated injuries and usurpations, all having in direct object the establishment of an absolute Tyranny over these States. To prove this, let Facts be submitted to a candid world...

In every stage of these Oppressions We have Petitioned for Redress in the most humble terms: Our repeated Petitions have been answered only by repeated injury. A Prince whose character is thus marked by every act which may define a Tyrant, is unfit to be the ruler of a free people.

Nor have We been wanting in attentions to our Brittish brethren. We have warned them from time to time of attempts by their legislature to extend an unwarrantable jurisdiction over us. We have reminded them of the circumstances of our emigration and settlement here. We have appealed to their native justice and magnanimity, and we have conjured them by the ties of our common kindred to disavow these usurpations, which, would inevitably interrupt our connections and correspondence. They too have been deaf to the voice of justice and of consanguinity. We must, therefore, acquiesce in the necessity, which denounces our Separation, and hold them, as we hold the rest of mankind, Enemies in War, in Peace Friends."

Jesus' Return
Contrary to the concept of Jesus as peaceful, He will return to destroy Satan's world empire and erect an eternal kingdom of righteousness, with Christian saints as His army.

Revelation 19:11 And I saw heaven opened, and behold a white horse; and he that sat upon him was called Faithful and True, and in righteousness he doth judge and make war. 12 His eyes were as a flame of fire, and on his head were many crowns; and he had a name written, that no man knew, but he himself. 13 And he was clothed with a vesture dipped in blood: and his name is called The Word of God. 14 And the armies which were in heaven followed him upon white horses, clothed in fine linen, white and clean. 15 And out of his mouth goeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and wrath of Almighty God. 16 And he hath on his vesture and on his thigh a name written, King Of Kings, And Lord Of Lords. 17 And I saw an angel standing in the sun; and he cried with a loud voice, saying to all the fowls that fly in the midst of heaven, Come and gather yourselves together unto the supper of the great God; 18 That ye may eat the flesh of kings, and the flesh of captains, and the flesh of mighty men, and the flesh of horses, and of them that sit on them, and the flesh of all men, both free and bond, both small and great. 19 And I saw the beast, and the kings of the earth, and their armies, gathered together to make war against him that sat on the horse, and against his army. 20 And the beast was taken, and with him the false prophet that wrought miracles before him, with which he deceived them that had received the mark of the beast, and them that worshipped his image. These both were cast alive into a lake of fire burning with brimstone. 21 And the remnant were slain with the sword of him that sat upon the horse, which sword proceeded out of his mouth: and all the fowls were filled with their flesh.

Revelation 6:14 And the heaven departed as a scroll when it is rolled together; and every mountain and island were moved out of their places. 15 And the kings of the earth, and the great men, and the rich men, and the chief captains, and the mighty men, and every bondman, and every free man, hid themselves in the dens and in the rocks of the mountains; 16 And said to the mountains and rocks, Fall on us, and hide us from the face of him that sitteth on the throne, and from the wrath of the Lamb: 17 For the great day of his wrath is come; and who shall be able to stand?

Jesus warned His enemies of His return:

Luke 13:34 O Jerusalem, Jerusalem, which killest the prophets, and stonest them that are sent unto thee; how often would I have gathered thy children together, as a hen doth gather her brood under her wings, and ye would not! 35 Behold, your house is left unto you desolate: and verily I say unto you, Ye shall not see me, until the time come when ye shall say, Blessed is he that cometh in the name of the Lord.

Matthew 23:37 O Jerusalem, Jerusalem, thou that killest the prophets, and stonest them which are sent unto thee, how often would I have gathered thy children together, even as a hen gathereth her chickens under her wings, and ye would not! 38 Behold, your house is left unto you desolate. 39 For I say unto you, Ye shall not see me henceforth, till ye shall say, Blessed is he that cometh in the name of the Lord.

Defense of Others
There may be cases where defending others might be justified, particularly when it is a life and death situation. While we are commanded not to avenge ourselves, it is commonly recognized that defense of others when they are in mortal danger is honorable.

Government
As previously mentioned, the Apostle Paul stated that God uses government violence to encourage good works and discourage bad ones. As such, governmental violence can be used to further God's will by promoting good over evil.

Romans 13:3 For rulers are not a terror to good works, but to the evil. Wilt thou then not be afraid of the power? do that which is good, and thou shalt have praise of the same: 4 For he is the minister of God to thee for good. But if thou do that which is evil, be afraid; for he beareth not the sword in vain: for he is the minister of God, a revenger to execute wrath upon him that doeth evil. 5 Wherefore ye must needs be subject, not only for wrath, but also for conscience sake. 6 For for this cause pay ye tribute also: for they are God's ministers, attending continually upon this very thing.

Stopping Global Evil/Protecting the Church's Reputation
Per the Declaration of Independence, there is a point where, as Edmund Burke once famously noted, "The only thing necessary for the triumph of evil is that good men do nothing." When it is in the power of good people to stop global evil, they are justified in exercising their inalienable rights per the Declaration of Independence.

This principle can be, to a degree, observed in 1 Corinthians 6, where the Apostle Paul urges legal matters between Christians to be settled within the Christian Church. As Paul observes, Christians will ultimately judge angels, and as such are all the more suited to judge matters in this life. While Paul nonetheless urges them to just take wrong instead, he does state that when problems arise within the Church, they should be handled by the Church.

1 Corinthians 6:1 Dare any of you, having a matter against another, go to law before the unjust, and not before the saints? 2 Do ye not know that the saints shall judge the world? and if the world shall be judged by you, are ye unworthy to judge the smallest matters? 3 Know ye not that we shall judge angels? how much more things that pertain to this life? 4 If then ye have judgments of things pertaining to this life, set them to judge who are least esteemed in the church. 5 I speak to your shame. Is it so, that there is not a wise man among you? no, not one that shall be able to judge between his brethren? 6 But brother goeth to law with brother, and that before the unbelievers. 7 Now therefore there is utterly a fault among you, because ye go to law one with another. Why do ye not rather take wrong? why do ye not rather suffer yourselves to be defrauded? 8 Nay, ye do wrong, and defraud, and that your brethren.

This follows after Paul, in the previous chapter, urged Christians to expel those who are engaged in clearly evil lifestyles that the Church might not be defamed.

1 Corinthians 5:1 It is reported commonly that there is fornication among you, and such fornication as is not so much as named among the Gentiles, that one should have his father's wife. 2 And ye are puffed up, and have not rather mourned, that he that hath done this deed might be taken away from among you. 3 For I verily, as absent in body, but present in spirit, have judged already, as though I were present, concerning him that hath so done this deed, 4 In the name of our Lord Jesus Christ, when ye are gathered together, and my spirit, with the power of our Lord Jesus Christ, 5 To deliver such an one unto Satan for the destruction of the flesh, that the spirit may be saved in the day of the Lord Jesus. 6 Your glorying is not good. Know ye not that a little leaven leaveneth the whole lump? 7 Purge out therefore the old leaven, that ye may be a new lump, as ye are unleavened. For even Christ our passover is sacrificed for us: 8 Therefore let us keep the feast, not with old leaven, neither with the leaven of malice and wickedness; but with the unleavened bread of sincerity and truth. 9 I wrote unto you in an epistle not to company with fornicators: 10 Yet not altogether with the fornicators of this world, or with the covetous, or extortioners, or with idolaters; for then must ye needs go out of the world. 11 But now I have written unto you not to keep company, if any man that is called a brother be a fornicator, or covetous, or an idolator, or a railer, or a drunkard, or an extortioner; with such an one no not to eat. 12 For what have I to do to judge them also that are without? do not ye judge them that are within? 13 But them that are without God judgeth. Therefore put away from among yourselves that wicked person.

One might reasonably conclude that, were such a person unwilling to leave Church property while engaged in a lifestyle that destroys God's reputation, they could be forced to leave through force in the same way that Jesus used force to make those misusing God's temple leave. (Luke 19:45)
