Contradiction with Ezekiel 18:20
This verse indicates individual responsibility for sin and death, suggesting death comes from one's own sin rather than through man (as stated in 1 Corinthians 15:21).
Ezekiel 18:20: The soul that sinneth, it shall die. The son shall not bear the iniquity of the father, neither shall the father bear the iniquity of the son: the righteousness of the righteous shall be upon him, and the wickedness of the wicked shall be upon him.
Contradiction with Romans 5:12
While this verse aligns with 1 Corinthians 15:21 by attributing death to sin entering through one man, it emphasizes sin as the reason for death rather than directly attributing it to the act of one man.
Romans 5:12: Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned: [for that: or, in whom]
Contradiction with Genesis 2:17
This verse says death comes as a direct command from God as a consequence of eating the fruit, suggesting divine decree rather than the act of one man as the cause of death.
Genesis 2:17: But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die. [thou shalt surely...: Heb. dying thou shalt die]
Paradox #1
The potential contradiction is the idea that death came into the world through one man, which conflicts with the scientific understanding of death as a natural part of life long before humans existed. According to science, life and death have been part of the natural biological processes on Earth for millions of years.
Paradox #2
One potential contradiction in 1 Corinthians 15:21 could be the idea that death and resurrection both come through individuals (Adam and Christ), which could conflict with the belief in individual accountability. Some might see a moral inconsistency in being affected by the actions of these individuals rather than solely one's own choices.
