Contradiction with Matthew 23:11
This verse suggests that the greatest among you shall be your servant, which contrasts with the elevation of a child-like status in greatness in Luke 9:48.
Matthew 23:11: But he that is greatest among you shall be your servant.
Contradiction with Mark 9:35
It states that to be first, one must be last and servant of all, a concept that introduces a service-oriented contradiction to the child humility focus in Luke 9:48.
Mark 9:35: And he sat down, and called the twelve, and saith unto them, If any man desire to be first, [the same] shall be last of all, and servant of all.
Contradiction with Matthew 19:30
This verse suggests the first will be last and the last will be first, which contradicts with the specific childlike reception to greatness mentioned in Luke 9:48.
Matthew 19:30: But many [that are] first shall be last; and the last [shall be] first.
Contradiction with Matthew 18:4
Although similar, the requirement of humility to be the greatest in the kingdom is subtly contradicted by the reception of children rather than becoming like them.
Matthew 18:4: Whosoever therefore shall humble himself as this little child, the same is greatest in the kingdom of heaven.
