Contradiction with Matthew 2:11
This verse describes the wise men visiting Jesus in a house, not in a manger, contradicting the setting of Luke 2:12.
Matthew 2:11: And when they were come into the house, they saw the young child with Mary his mother, and fell down, and worshipped him: and when they had opened their treasures, they presented unto him gifts; gold, and frankincense, and myrrh. [presented: or, offered]
Contradiction with John 7:27
This verse suggests uncertainty about Jesus' origins, whereas Luke 2:12 specifies a clear sign of Jesus' birth.
John 7:27: Howbeit we know this man whence he is: but when Christ cometh, no man knoweth whence he is.
Contradiction with Mark 6:3
This verse identifies Jesus as the carpenter, which contrasts with the infant portrayal in Luke 2:12.
Mark 6:3: Is not this the carpenter, the son of Mary, the brother of James, and Joses, and of Juda, and Simon? and are not his sisters here with us? And they were offended at him. [offended: scandalized in, or, by him]
