Contradiction with Matthew 2:13-15
These verses describe Joseph, Mary, and Jesus fleeing to Egypt, suggesting they were not in Nazareth at all times as implied by their annual visit to Jerusalem for the feast.
Matthew 2:13-15: And when they were departed, behold, the angel of the Lord appeareth to Joseph in a dream, saying, Arise, and take the young child and his mother, and flee into Egypt, and be thou there until I bring thee word: for Herod will seek the young child to destroy him.
Contradiction with John 7:5
This verse indicates that even Jesus' brothers did not believe in him at first, which contradicts the idea of a harmonious and devout family regularly attending religious festivals.
John 7:5: For neither did his brethren believe in him.
Contradiction with Luke 4:16
This verse states that it was Jesus’ custom to go to the synagogue on the Sabbath, which contrasts with the idea of a single yearly journey to Jerusalem being emphasized in Luke 2:41.
Luke 4:16: And he came to Nazareth, where he had been brought up: and, as his custom was, he went into the synagogue on the sabbath day, and stood up for to read.
