Well the post 2,991 was addressed to me so I thought you were asking me.
I was just using the term *Protestant* in the general sense of *non-Catholic*, barring LDS or JW’s which are recognized as cults by everyone but themselves, for simplicity’s sake.
I never explored Unitarian doctrine and never had much need or desire to, so I’ve never given your question much thought. I don’t know right now.
IOW it is not possible to "know" what Unitarians believe. Any person who purports to is either a liar or arrogantly stupid.
