Contradiction with Matthew 19:6
This verse states that what God has joined together, let no one separate, suggesting marriages should not be broken, contradicting the permission for separation found in 1 Corinthians 7:12.
Matthew 19:6: Wherefore they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder.
Contradiction with Malachi 2:16
This verse states that God hates divorce, which contradicts the allowance for separation in 1 Corinthians 7:12.
Malachi 2:16: For the LORD, the God of Israel, saith that he hateth putting away: for [one] covereth violence with his garment, saith the LORD of hosts: therefore take heed to your spirit, that ye deal not treacherously. [that he...: or, if he hate her, put her away] [putting...: Heb. to put away]
Contradiction with Mark 10:9
Similar to Matthew 19:6, this verse implies the permanence of marriage, contrasting the allowance for marital separation in 1 Corinthians 7:12.
Mark 10:9: What therefore God hath joined together, let not man put asunder.
Contradiction with Romans 7:2-3
These verses state that a married woman is bound to her husband as long as he lives, contradicting the permissiveness towards separation in 1 Corinthians 7:12.
Romans 7:2-3: For the woman which hath an husband is bound by the law to [her] husband so long as he liveth; but if the husband be dead, she is loosed from the law of [her] husband.
Contradiction with Matthew 5:32
This verse adds a condition for divorce that is not explicitly mentioned in 1 Corinthians 7:12, presenting a potential contradiction in terms of grounds for separation.
Matthew 5:32: But I say unto you, That whosoever shall put away his wife, saving for the cause of fornication, causeth her to commit adultery: and whosoever shall marry her that is divorced committeth adultery.
Paradox #1
Some might see a moral inconsistency in 1 Corinthians 7:12 due to its advice being presented as the personal opinion of Paul, rather than a direct command from God. This could lead to questions about the divine authority or consistency of this guidance compared to other biblical directives.
