Contradiction with James 1:5
James 1:5 encourages believers to seek wisdom from God, implying that wisdom is a gift from God, not something inherently possessed by a teacher as suggested in Romans 2:20.
James 1:5: If any of you lack wisdom, let him ask of God, that giveth to all [men] liberally, and upbraideth not; and it shall be given him.
Contradiction with 1 Corinthians 8:2
This verse indicates that if anyone thinks they know anything, they do not yet know as they ought to know, contrasting with the confidence in knowledge implied by Romans 2:20.
1 Corinthians 8:2: And if any man think that he knoweth any thing, he knoweth nothing yet as he ought to know.
Contradiction with Matthew 23:24
Jesus criticizes the teachers of the law for their hypocrisy, contradicting the claim in Romans 2:20 of instructors in the law being guides to the blind.
Matthew 23:24: [Ye] blind guides, which strain at a gnat, and swallow a camel.
Contradiction with 1 Corinthians 13:9
This verse acknowledges that our knowledge is partial and incomplete, contrasting with the suggestion in Romans 2:20 of possessing full knowledge by teaching the law.
1 Corinthians 13:9: For we know in part, and we prophesy in part.
Contradiction with Jeremiah 8:8-9
This passage questions the wisdom of those who claim to be wise because they have the law, which contrasts with the description in Romans 2:20 of being knowledgeable through the law.
Jeremiah 8:8-9: How do ye say, We [are] wise, and the law of the LORD [is] with us? Lo, certainly in vain made he [it]; the pen of the scribes [is] in vain. [in vain made...: or, the false pen of the scribes worketh for falsehood]
Paradox #1
Romans 2:20 speaks about being a teacher of others while having knowledge and truth. The contradiction could be the idea of someone teaching others the correct way to live or act but not following those teachings themselves. This inconsistency is about saying one thing and doing another, which can be seen as hypocritical.
