Contradiction with Mark 6:5
This verse shows that even Jesus could not perform miracles in his hometown, implying a limitation in the distribution of the gifts of healing.
Mark 6:5: And he could there do no mighty work, save that he laid his hands upon a few sick folk, and healed [them].
Contradiction with 2 Timothy 4:20
Paul leaves Trophimus sick, suggesting not all possess the gift of healing, which contrasts with the distribution of healing mentioned in 1 Corinthians 12:9.
2 Timothy 4:20: Erastus abode at Corinth: but Trophimus have I left at Miletum sick.
Contradiction with John 5:3-9
Jesus heals only one man at the pool, not all present, contradicting the idea of widespread distribution of healing gifts.
John 5:3-9: In these lay a great multitude of impotent folk, of blind, halt, withered, waiting for the moving of the water.
Contradiction with Philippians 2:27
Epaphroditus was sick nearly unto death, yet was healed by God's mercy, not specifically through the spiritual gift Paul speaks of.
Philippians 2:27: For indeed he was sick nigh unto death: but God had mercy on him; and not on him only, but on me also, lest I should have sorrow upon sorrow.
