Contradiction with Romans 6:15
This verse questions whether grace allows continued sin, whereas Galatians 2:18 implies rebuilding what was destroyed is transgression.
Romans 6:15: What then? shall we sin, because we are not under the law, but under grace? God forbid.
Contradiction with 1 Corinthians 15:56
This verse states that the law gives sin its power, contradicting Galatians 2:18's indication of a return to the law implying transgression.
1 Corinthians 15:56: The sting of death [is] sin; and the strength of sin [is] the law.
Contradiction with Hebrews 10:26
Suggests willful sin after knowledge of truth negates sacrifice for sins, differing from the rebuilding theme in Galatians 2:18.
Hebrews 10:26: For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins,
Contradiction with James 1:25
Commends continuing in the law of liberty, contrasting Galatians 2:18’s notion of transgression in rebuilding the law.
James 1:25: But whoso looketh into the perfect law of liberty, and continueth [therein], he being not a forgetful hearer, but a doer of the work, this man shall be blessed in his deed. [deed: or, doing]
Contradiction with Galatians 3:10
Declares those relying on the law are cursed, conflicting with Galatians 2:18’s implication that rebuilding the law is a transgression.
Galatians 3:10: For as many as are of the works of the law are under the curse: for it is written, Cursed [is] every one that continueth not in all things which are written in the book of the law to do them.
Paradox #1
Galatians 2:18 might be seen as contradictory if one misunderstands it as encouraging a return to old laws after embracing a new faith through Jesus. Paul stresses not rebuilding what was once abandoned (the law) after accepting the new covenant of faith. It could seem inconsistent if taken out of this context, appearing to suggest a return to old obligations after accepting grace.
