Contradiction with Mark 6:1-4
Mark 6:4 indicates that a prophet has no honor in his own country, whereas John 4:43 suggests he would be accepted in Galilee, his own country.
Mark 6:1-4: And he went out from thence, and came into his own country; and his disciples follow him.
Contradiction with Matthew 13:57
Similar to Mark 6:4, implies lack of honor for a prophet in his own country, contradicting the acceptance noted in John 4:43.
Matthew 13:57: And they were offended in him. But Jesus said unto them, A prophet is not without honour, save in his own country, and in his own house.
