Contradiction with Romans 14:23
This verse states that whatever is not of faith is sin, which contradicts Matthew 16:8 where Jesus points out the disciples' lack of faith but doesn't call it a sin.
Romans 14:23: And he that doubteth is damned if he eat, because [he eateth] not of faith: for whatsoever [is] not of faith is sin. [doubteth: or, discerneth and putteth a difference between meats] [damned: or, condemned, or liable to punishment]
Contradiction with James 1:6-7
This passage emphasizes that those who doubt should not expect to receive anything from the Lord, conflicting with Matthew 16:8 where Jesus, despite pointing out their doubt, continues to teach and guide the disciples.
James 1:6-7: But let him ask in faith, nothing wavering. For he that wavereth is like a wave of the sea driven with the wind and tossed.
Contradiction with Matthew 17:20
Jesus says that even faith as small as a mustard seed can move mountains, suggesting that the disciples' lack of faith (as noted in Matthew 16:8) was smaller than this or ineffective, indicating a contradiction in the disciples' capacity for faith.
Matthew 17:20: And Jesus said unto them, Because of your unbelief: for verily I say unto you, If ye have faith as a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you.
Contradiction with Hebrews 11:6
States that without faith, it is impossible to please God, suggesting a stronger consequence than indicated in Matthew 16:8 where Jesus addresses the lack of faith without attaching an impossibility of pleasing God.
Hebrews 11:6: But without faith [it is] impossible to please [him]: for he that cometh to God must believe that he is, and [that] he is a rewarder of them that diligently seek him.
Contradiction with Mark 4:40
Jesus questions the disciples' fear and lack of faith in the midst of a storm, implying a scenario where fear overrides faith, contradicting the notion of working with limited faith in Matthew 16:8.
Mark 4:40: And they feared exceedingly, and said one to another, What manner of man is this, that even the wind and the sea obey him?
