Contradiction with Romans 16:17
This verse advises avoiding those who cause divisions, while Matthew 16:6 warns against the teaching of the Pharisees and Sadducees, which can be seen as promoting a type of division.
Romans 16:17: Now I beseech you, brethren, mark them which cause divisions and offences contrary to the doctrine which ye have learned; and avoid them.
Contradiction with 1 Corinthians 5:6
This verse talks about how a little leaven leavens the whole lump, suggesting an acknowledgment of subtle influence, whereas Matthew 16:6 warns against such influence specifically from the Pharisees and Sadducees.
1 Corinthians 5:6: Your glorying [is] not good. Know ye not that a little leaven leaveneth the whole lump?
Contradiction with Galatians 5:9
Similar to 1 Corinthians 5:6, it acknowledges the effect of leaven, thereby indirectly supporting the caution in Matthew 16:6, but in a broader context beyond the Pharisees and Sadducees specifically.
Galatians 5:9: A little leaven leaveneth the whole lump.
Contradiction with Matthew 5:14
This verse states that a city on a hill cannot be hidden, promoting visibility and clarity, while Matthew 16:6 implies a hidden, potentially harmful influence through the metaphor of leaven.
Matthew 5:14: Ye are the light of the world. A city that is set on an hill cannot be hid.
Contradiction with Luke 12:1
Unlike Matthew 16:6 which is directed specifically at the doctrines, this verse broadens the warning about hypocrisy, potentially creating confusion about the nature of the warning.
Luke 12:1: In the mean time, when there were gathered together an innumerable multitude of people, insomuch that they trode one upon another, he began to say unto his disciples first of all, Beware ye of the leaven of the Pharisees, which is hypocrisy.
Paradox #1
Matthew 16:6 contains Jesus' warning about the "yeast of the Pharisees and Sadducees," referring to their teachings and hypocrisy. A contradiction might be seen in Jesus criticizing these religious leaders for their hypocrisy while biblical texts also call for respect toward authority figures. This could be viewed as a tension between challenging wrongdoing and maintaining respect for leaders.
