Contradiction with Matthew 6:6
Luke 8:51 describes Jesus performing a miracle with a select few present, while Matthew 6:6 emphasizes praying in private, suggesting miracles should also be private.
Matthew 6:6: But thou, when thou prayest, enter into thy closet, and when thou hast shut thy door, pray to thy Father which is in secret; and thy Father which seeth in secret shall reward thee openly.
Contradiction with Matthew 13:58
Luke 8:51 involves Jesus allowing specific people to witness the miracle, whereas Matthew 13:58 notes that Jesus did not perform many miracles due to the unbelief in the area, implying belief as a prerequisite.
Matthew 13:58: And he did not many mighty works there because of their unbelief.
Contradiction with John 2:24-25
Luke 8:51 shows Jesus taking specific disciples and parents with him, but John 2:24-25 mentions Jesus not entrusting himself to people, which seems to contradict the selective inclusion.
John 2:24-25: But Jesus did not commit himself unto them, because he knew all [men],
Contradiction with Mark 7:33-34
Luke 8:51 involves a public setting with a controlled audience, whereas Mark 7:33-34 shows Jesus performing a miracle in private, only with those healed.
Mark 7:33-34: And looking up to heaven, he sighed, and saith unto him, Ephphatha, that is, Be opened.
Contradiction with John 7:4
Luke 8:51 restricts the audience for the miracle, whereas John 7:4 suggests that if Jesus desires to be known openly, he shouldn’t act in secret.
John 7:4: For [there is] no man [that] doeth any thing in secret, and he himself seeketh to be known openly. If thou do these things, shew thyself to the world.
