Contradiction with John 5:19
Matthew 9:8 emphasizes the power given to man, but John 5:19 highlights that the Son can do nothing by himself, only what he sees the Father doing.
John 5:19: Then answered Jesus and said unto them, Verily, verily, I say unto you, The Son can do nothing of himself, but what he seeth the Father do: for what things soever he doeth, these also doeth the Son likewise.
Contradiction with Isaiah 42:8
Matthew 9:8 attributes power to men, whereas Isaiah 42:8 states God shares His glory with no other, implying divine acts aren’t attributed to men.
Isaiah 42:8: I [am] the LORD: that [is] my name: and my glory will I not give to another, neither my praise to graven images.
Contradiction with Jeremiah 17:5
Matthew 9:8 speaks of man doing something wondrous, while Jeremiah 17:5 cautions against trusting in man over God.
Jeremiah 17:5: Thus saith the LORD; Cursed [be] the man that trusteth in man, and maketh flesh his arm, and whose heart departeth from the LORD.
Contradiction with Psalm 115:1
Matthew 9:8 attributes glory to men seeing divine acts, whereas Psalm 115:1 redirects all glory to God alone.
Psalm 115:1: Not unto us, O LORD, not unto us, but unto thy name give glory, for thy mercy, [and] for thy truth's sake.
Paradox #1
The potential contradiction in Matthew 9:8 could be the confusion between attributing the power to forgive sins to a person or only to God, which may conflict with certain beliefs about divine authority.
