And that is assuredly not the Anglicanism of the great Caroline Divines my Catholic Grandfather had me read (Lancelot Andrewes & Co.) who would have chewed you up (and me too for that matter) in a New York minute.
Charity is in short supply here, so I will restrict myself to saying that what is celebrated in my church is what I read from the Missals and lectionaries. We have no IC service, so there is no mention of it liturgically. It is a private pious belief on the part of a parishioner. So far as the Church is concerned, the BVM is the Theotokos and that's that.
In Christ,
Deacon Paul+
