The Protestant Reformers affirmed their belief
that Mary, while remaining every-virgin, was
truly the Mother of God.
Martin Luther
(1483-1546)
It is an article of faith that Mary is Mother of the
Lord and still a virgin. ...
Christ, we believe, came forth from a womb left perfectly intact.
(Weimer's The
Works of Luther, English translation
by Pelikan, Concordia,
St. Louis, v. 11, pp. 319-320; v. 6. p. 510.)
This immaculate and perpetual virginity forms,
therefore, the just theme
of our eulogy. Such was the work of the Holy Ghost, who
at the Conception
and birth of the Son so favoured the Virgin Mother as
to impart to her
fecundity while preserving inviolate her perpetual
virginity."
(Weimer's, v. 7, p. 572)
