Thank you Buck for your very sincere retraction. You have honored this thread and site.
Perhaps now, we can continue the discussion related to in the rest of your post.
However, the issue is not whether any ONE Catholic is a Christian; it is whether Catholicism confers Christianity on all faithful adherents. I don’t think we have his statement on that point.
No church can confer Christianity on a single soul. It is completely between the individual and Christ. (”there is one mediator between God and man; the man Christ Jesus.”)
It seems neither you nor Buck W are interested in answers (they were given already). What you want is every poster to give answers a million times over.
