So if not Mary, who was the first Christian? She was there from the very start.
Interesting question. We don't know for sure. Hence, sheer speculation on your part.
>>Well, yes it is based on the what happened at the Cross when Jesus gave her to John....and only John. This is clear if you understand the Greek.<<
Except that neither Jesus nor John were speaking Greek. I'm not aware that the Aramaic used was recorded anywhere.
You presume they were speaking Aramaic.
However, what we do have is recorded in the Greek as determined by the Holy Spirit. The Greek does not support Rome's claim on this issue.
"What you've seen" is irrelevant. I've given you the official definitions as used by the Church. Show me where they have changed over time.
"Interesting question. We don't know for sure. Hence, sheer speculation on your part."
Who else is there?? The Bible doesn't record anyone other than Mary as "following Christ" for 30+ years. The Wedding at Cana seems pretty definitive to me.
"You presume they were speaking Aramaic."
Since Aramaic was the native language of Jesus, Mary, and John, it is highly likely that in the stressful situation at Golgotha, that is what was used.
