ABC:John 18

Verse 27
Infidels.org calls as a contradiction, "How many times did the cock crow?"

Mark 14:30 And Jesus saith unto him, Verily I say unto thee, That this day, even in this night, before the cock crow twice, thou shalt deny me thrice.

Mark 14:72 And the second time the cock crew. And Peter called to mind the word that Jesus said unto him, Before the cock crow twice, thou shalt deny me thrice. And when he thought thereon, he wept.

Matthew 26:74 Then began he to curse and to swear, saying, I know not the man. And immediately the cock crew. 75 And Peter remembered the word of Jesus, which said unto him, Before the cock crow, thou shalt deny me thrice. And he went out, and wept bitterly.

Luke 22:60 And Peter said, Man, I know not what thou sayest. And immediately, while he yet spake, the cock crew. 61 And the Lord turned, and looked upon Peter. And Peter remembered the word of the Lord, how he had said unto him, Before the cock crow, thou shalt deny me thrice.

John 13:38 Jesus answered him, Wilt thou lay down thy life for my sake? Verily, verily, I say unto thee, The cock shall not crow, still thou hast denied me thrice.

John 18:27 Peter then denied again: and immediately the cock crew.

The simple answer is twice, but only once after Jesus said this. The rooster had already crowed once, and Jesus predicted Peter would deny him three times before it crowed a second time. Therefore Peter did so before it crowed once more, a second time. There's nothing contradictory about these passages in the slightest.

Verse 11
TheThinkingAtheist.com claims the Bible is wrong about the following passage, and makes the following comments:

Matthew 27:11 And Jesus stood before the governor: and the governor asked him, saying, Art thou the King of the Jews? And Jesus said unto him, Thou sayest. 12 And when he was accused of the chief priests and elders, he answered nothing. 13 Then said Pilate unto him, Hearest thou not how many things they witness against thee? 14 And he answered him to never a word; insomuch that the governor marvelled greatly.

Jesus doesn’t answer the charges.

John 18:37 Pilate therefore said unto him, Art thou a king then? Jesus answered, Thou sayest that I am a king. To this end was I born, and for this cause came I into the world, that I should bear witness unto the truth. Every one that is of the truth heareth my voice.

Jesus answers the charges.

The translation the critic quotes uses the term "charge" to refer to the accusations of the "chief priests and elders." What we have here is a critic using a word they don't understand, namely charges. Charges are the accusations the priests and elders made against Jesus, not Pilate's curious questioning of Jesus. If the critic had any reading comprehension they would have noticed this. Jesus refused to answer the accusations the prosecution made, but did carry on a conversation with the judge about who He was, in other words. This really should have been quite obvious since John 18 also mentions Jesus responding to Pilate's questions.

Matthew 27:11 And Jesus stood before the governor: and the governor asked him, saying, Art thou the King of the Jews? And Jesus said unto him, Thou sayest.

It should have been very obvious that Pilate's questions were not considered charges like the accusations of the priests and elders. Either the critic didn't even bother reading the passage at all carefully to see this, making a careless accusation, or deliberately was dishonest in trying to make the passage appear to say something it didn't. Take your pick.
