Contradiction with Matthew 26:72
This verse contradicts Mark 14:69 as Matthew places Peter's second denial at a different moment and in return denies with an oath, emphasizing a different setting and intensity.
Matthew 26:72: And after a while came unto [him] they that stood by, and said to Peter, Surely thou also art [one] of them; for thy speech bewrayeth thee.
Contradiction with Luke 22:58
Luke suggests a shorter time gap between the first and second denial compared to Mark's narrative.
Luke 22:58: And after a little while another saw him, and said, Thou art also of them. And Peter said, Man, I am not.
Contradiction with John 18:25
John's account presents a slightly different scenario and audience for Peter's denials compared to Mark 14:69, leading to a different interpretation of the events.
John 18:25: And Simon Peter stood and warmed himself. They said therefore unto him, Art not thou also [one] of his disciples? He denied [it], and said, I am not.
