I am sorry, ozzy, it is not possible to be a “nominal Christian”.
You are either a Christian or you are not, however your statement explains much.
Sorry, I didn’t know you were the judge of who is a Christian. Forgive me, God. When I said I was a nominal Christian, I meant that my parents made me attend Sunday School. I haven’t been back to church since, but I haven’t joined any other religion. If that doesn’t fit your definition, that’s OK too.
Perhaps he meant that he knew very little about Christianity's teachings; other than he is trusting in Jesus (of the bible) to assure his salvation.
