You seem to be under the erroneous impression that Mary worship is accepted.
Depends on what one means by "barely." Luke devotes two whole chapters to Mary, and in what connection? With the incarnation. Look at the histoic creeds: THE GOD is incarnate by the Virgin Mary. Note it does not say "born of A virgin." . The cult of Mary is not a concoction of the Middle Ages but can be traced to the early Church Fathers, such as Ignatious who proves the divinity of Jesus by reference to the Virgin. The claim--a claim not made by the way by Luther or Calvin--that Mary was a virgin at the time of the conception but not thereafter, tends to diminish not only Mary but Jesus. Contrarily, the exaltation of Mary elevates Jesus. The term Theotokos arises out of the Arian and Nestorian controversies and are part of the definition of the Trinity. Muslims have an inkling of this, assumed, one gathers from heretical sects in Syria which DID make Mary one of the Trinity. The worst that some Marianists in the Catholic Church have done is to raise Mary to demi-god status. But the modern day Protestants go so far in the opposite direction as to put here on the same level as Elizabeth or a Old Testament prototype like Hannah or Sarah. Her originally virginity reduced to a sign and Mary's role in the event a purely passive one. This, IMO. disregards the intent of St. Luke.
