Contradiction with Matthew 12:50
Luke 8:19 speaks of Jesus' biological family seeking him, yet Matthew 12:50 expands the notion of family beyond biological ties, suggesting that whoever does the will of the Father is part of Jesus’ family.
Matthew 12:50: For whosoever shall do the will of my Father which is in heaven, the same is my brother, and sister, and mother.
Contradiction with Matthew 10:37
This verse emphasizes putting Jesus above one’s own family, whereas Luke 8:19 notes the physical presence and involvement of Jesus’ family in his life.
Matthew 10:37: He that loveth father or mother more than me is not worthy of me: and he that loveth son or daughter more than me is not worthy of me.
Contradiction with John 7:5
Luke 8:19 depicts Jesus' family as being present and possibly supportive, but John 7:5 indicates that even Jesus' brothers did not believe in him.
John 7:5: For neither did his brethren believe in him.
Contradiction with Mark 3:21
In contrast to Luke 8:19, where Jesus' family seeks him, Mark 3:21 illustrates his family's concern about his mental state, suggesting they thought he was "beside himself."
Mark 3:21: And when his friends heard [of it], they went out to lay hold on him: for they said, He is beside himself. [friends: or, kinsmen]
Contradiction with Luke 14:26
This verse asserts a priority for allegiance to Jesus over familial bonds, which contrasts with the depiction of the family trying to access Jesus in Luke 8:19.
Luke 14:26: If any [man] come to me, and hate not his father, and mother, and wife, and children, and brethren, and sisters, yea, and his own life also, he cannot be my disciple.
Paradox #1
Some people point out that in the accounts of Jesus' family visiting him, the details and order of events differ slightly between the Gospels of Mark, Matthew, and Luke. This can be seen as a minor inconsistency.
