Some argue that the Bible is contradictory concerning whether God is the author of confusion. The argument is that 1 Corinthians 14:33 says that God is not the author of confusion, but Genesis 11:8-9 says that God confused the languages of the earth at the Tower of Babel. However, there is a very simple explanation that eliminates this supposed contradiction.
For God is not a God of confusion but of peace. As in all the churches of the saints,
1 Corinthians 14:33
8 So the Lord dispersed them from there over the face of all the earth, and they left off building the city. 9 Therefore its name was called Babel, because there the Lord confused[a] the language of all the earth. And from there the Lord dispersed them over the face of all the earth.
Genesis 11:8-9
The context of 1 Corinthians 14:33 is completely different from the context of Genesis 11:8-9. 1 Corinthians 14:33 is about ”’worship being done in an orderly manner”’, which has absolutely nothing to do with what is happening in Genesis 11:8-9.
The context of 1 Corinthians 14:33 is that the Corinthian church was using spiritual gifts in a way that was causing disorder in the church. We can perhaps paraphrase 1 Corinthians 14:33 to say, “For God is not a God who should be worshipped in a confused manner, but a God who should be worshipped in an orderly and peaceful manner.”
So, there is no contradiction between Genesis 11:8-9 and 1 Corinthians 14:33 because the two passages really have nothing to do with each other.
