I have not heard from you in a long time, P-Marlowe. Welcome back.
In everyday conversation, I use Christian much the same way most English speakers use the word:
Christian 1 a : one who professes belief in the teachings of Jesus Christ b : DISCIPLE (Merriam-Webster Dictionary)
For those who insist on a Biblical definition of the word (which appears just three places in the KJV), I cite Acts 11:26:
. . . So for a whole year Barnabas and Saul met with the church and taught great numbers of people. The disciples were called Christians first at Antioch.
In short, a Christian is a disciple of Jesus Christ.
So anyone who claims to follow somebody named Jesus Christ is a Christian in your book, no matter what doctrine he holds about who exactly that person was?
Do you believe that in order to be a Christian you have to believe that Jesus Christ is and was the Eternal God, the creator of all things?
Or is it OK to believe that he was either a prophet or "a God" among other Gods, or that he was at some point something other than God?
Jesus said that "Unless you believe that I AM, you will die in your sins." Do you believe that?
