The fact that heresy has plagued the “Church” is only too obvious to need explanation or example, and the Holy Spirit cannot be left holding the bag. He has preserved truth, even if it seemed a small spark in times of almost universal darkness, in the most unlikely places and among the most unlikely people, not always of the “Church” properly, but of the Church spiritually. Mankind is exceedingly capable of extrapolating sound doctrine into the most heinous error, even by many of those that you venerate as Church Fathers.
And no, the Church (those universally united to Christ by the Holy Spirit through faith) does not believe that Christ proceeds from Mary, continues to proceed from Mary, and is contained, supported by, and is conveyed to men through the conduit of Mary, as your doctrine and your artwork depict.
Sure, though the usual abbreviation is "BVM". :)
"And no, the Church (those universally united to Christ by the Holy Spirit through faith) does not believe that Christ proceeds from Mary, continues to proceed from Mary,..."
The Church does not believe that Christ "proceeds" (what a lousy English translation of "εκπορευόμενον" which refers to the Holy Spirit, not Christ, BTW)from anyone. Christ is "τόν Υιόν του Θεού τόν μονογενή, τόν εκ του Πατρός γεννηθέντα πρό πάντων τών αιώνων. Φώς εκ φωτός, Θεόν αληθινόν εκ Θεού αληθινού γεννηθέντα, ού ποιηθέντα, ομοούσιον τώ Πατρί, δι’ ού τά πάντα εγένετο.(And in one Lord Jesus Christ, the only-begotten Son of God, begotten of the Father before all aeons, Light of Light, true God of true God, begotten, not made, being of one essence with the Father;)"
"...and is contained, supported by, and is conveyed to men through the conduit of Mary, as your doctrine and your artwork depict."
Wherever do you get your theology and what you believe, apparently sincerely, is the theology of The Church?
