I have never tried to hide my church membership. That was a false accusation. But so far I have not seen any apology, just an excuse.
Nevertheless, your excuse is accepted.
I could be talking to an atheist, a non-trinitarian, a Muslim, Buddhist, Jew, anyone. Among Christians there are so many denominations, so many splinters, each having their own "flavor" that it is impossible to know what the other person believes unless it is clearly stated.
Neither you, nor others in your camps so to say, have clearly identified what denomination they belong to and what personal beliefs they hold. It makes a discussion a lot more meaningful if someone openly states "I don't believe Mary is a Mother of God" rather than present an ambiguous "Protestant" facade.
I thank you for your link. I take it that you are trinitarian yet somehow deny that Mary if the Mother of God?
