ABC:Luke 1

Verse 6
TheThinkingAtheist.com claims the Bible is wrong about the following passage in the section "Can Man Be Righteous?", and makes the following comments:

Genesis 7:1 ¶ And the LORD said unto Noah, Come thou and all thy house into the ark; for thee have I seen righteous before me in this generation.

Noah was righteous.

Job 2:3 And the LORD said unto Satan, Hast thou considered my servant Job, that there is none like him in the earth, a perfect and an upright man, one that feareth God, and escheweth evil? and still he holdeth fast his integrity, although thou movedst me against him, to destroy him without cause.

Job was righteous.

Luke 1:6 And they were both righteous before God, walking in all the commandments and ordinances of the Lord blameless.

Zechariah and Elizabeth were righteous.

James 5:16 Confess your faults one to another, and pray one for another, that ye may be healed. The effectual fervent prayer of a righteous man availeth much.

Some men are righteous, and their prayers are effective.

1 John 3:7 Little children, let no man deceive you: he that doeth righteousness is righteous, even as he is righteous.

Christians become righteous.

Romans 3:10 As it is written, There is none righteous, no, not one:

No one is righteous.

The simple answer is that there are two kinds of righteousness, Biblically, and Paul himself makes this plain. In fact, the entire book of Romans has as perhaps its major theme the contrast between the righteousness of the Law which noone measures up to, and the righteousness through faith which comes by trusting Jesus. Paul is contrasting two types of righteousness, a self-centered righteousness based on our works by which none will be justified because none are good enough in themselves, and a God-centered righteousness based on trusting Jesus to save us where it is God's righteousness that is credited to our accounts.

Romans 10:3 For they being ignorant of God's righteousness, and going about to establish their own righteousness, have not submitted themselves unto the righteousness of God. 4 For Christ is the end of the law for righteousness to every one that believeth. 5 For Moses describeth the righteousness which is of the law, That the man which doeth those things shall live by them. 6 But the righteousness which is of faith speaketh on this wise, Say not in thine heart, Who shall ascend into heaven? (that is, to bring Christ down from above:) 7 Or, Who shall descend into the deep? (that is, to bring up Christ again from the dead.) 8 But what saith it? The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach; 9 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. 10 For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation. 11 For the scripture saith, Whosoever believeth on him shall not be ashamed. Romans 3:19 ¶ Now we know that what things soever the law saith, it saith to them who are under the law: that every mouth may be stopped, and all the world may become guilty before God. 20 Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin. 21 But now the righteousness of God without the law is manifested, being witnessed by the law and the prophets; 22 Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference: 23 For all have sinned, and come short of the glory of God; 24 Being justified freely by his grace through the redemption that is in Christ Jesus: 25 Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God; 26 To declare, I say, at this time his righteousness: that he might be just, and the justifier of him which believeth in Jesus. 27 Where is boasting then? It is excluded. By what law? of works? Nay: but by the law of faith. 28 Therefore we conclude that a man is justified by faith without the deeds of the law.

There is no contradiction here. Paul is contrasting two types of righteousness, a righteousness according to the Law of works that nobody but Jesus measures up to, and a righteousness of faith where God credits righteousness based on trust in Jesus.

Romans 4:1 ¶ What shall we say then that Abraham our father, as pertaining to the flesh, hath found? 2 For if Abraham were justified by works, he hath whereof to glory; but not before God. 3 For what saith the scripture? Abraham believed God, and it was counted unto him for righteousness. 4 Now to him that worketh is the reward not reckoned of grace, but of debt. 5 But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness. 6 Even as David also describeth the blessedness of the man, unto whom God imputeth righteousness without works, 7 Saying, Blessed are they whose iniquities are forgiven, and whose sins are covered. 8 Blessed is the man to whom the Lord will not impute sin.

Verse 20
TheThinkingAtheist.com claims a contradiction here, asking "Who Did the Angel Speak to Regarding the Birth of Jesus? [Mary or Joseph]"

Matthew 1:20 But while he thought on these things, behold, the angel of the Lord appeared unto him in a dream, saying, Joseph, thou son of David, fear not to take unto thee Mary thy wife: for that which is conceived in her is of the Holy Ghost.

Luke 1:28 And the angel came in unto her, and said, Hail, thou that art highly favoured, the Lord is with thee: blessed art thou among women.

Obviously the angel spoke to both of them. As pointed out in the note for Matthew 1:16 the genealogy provided in Matthew is for Joseph while the genealogy in Luke is for Mary. The detail given in the early chapters of Matthew appears to be from Joseph's perspective whereas the detail given in the chapters of Luke from Mary's perspective. Thus, Joseph in the book of Matthew relates his experience with an angel, while Mary in the book of Luke relates her experience. Whether it was the same angel or different angels is uncertain.
