Oh come on, don’t make him have to take his Bible out of the plastic wrap! He already said he likes Two Corinthians!/he probably limes other Greeks too!
Last time I checked, when you are saved, there is NOT a theology test.
If God had a theology test, we would all be in trouble.
That’s not to say we should not study and try as hard as we can to understand the Word, but I am sure the thief on the cross did not know his scriptures — he simply believed and was saved.
There are a lot of people who won’t profess the name of Jesus, but claim to be Christians.
You may find yourselves humorous but to me to make fun of his faith is not a joke. Whether he is a “true” Christian is not your place to judge. That is between he and God. Hopefully God will be more compassionate and forgiving of you than you are of others.
