I think Matchett-PI was referring to DouglasKC, not you Xenia.
It’s difficult to dialog with restorationist types (e.g., Jehovah’s Witnesses, WWCOG, Campbellites, modern “messianic Jews”) because they have no historical frame of reference. In large part they deny the validity of the ecumenical creeds, and thus refuse to accept the orthodoxy that has been a hallmark of the universal church.
They are thus free to reinterpret history to support their restorationist theories, which are way outside of the mainstream of Christian theology for the most part.
