Contradiction with Matthew 26:63
Jesus remained silent before the high priest but later answered him, which contrasts with Matthew 27:14, where he remains silent before Pilate and does not respond at all.
Matthew 26:63: Jesus saith unto him, Thou hast said: nevertheless I say unto you, Hereafter shall ye see the Son of man sitting on the right hand of power, and coming in the clouds of heaven.
Contradiction with Mark 15:5
This verse affirms Jesus' silence before Pilate, similar to Matthew 27:14, and therefore does not directly contradict it.
Mark 15:5: But Jesus yet answered nothing; so that Pilate marvelled.
