Over at the latest website of Sentire cum Ecclesia (whereby David Schütz appears to be on the way to as many instantiations as Doctor Who), yours truly has been intervening in a big way in the discussion about what is meant by Our Lady's virginity in partu, attempting to defend the traditional doctrine thereof.
(Warning: this topic is sometimes discussed with too much expatiation of details that really require a holy reserve.)
With the Church, we pray in honour of the Ever-Virgin (from the Dominican Little Office of Our Lady):
Dignare me laudare te, Virgo sacrata: da mihi virtutem contra hostes tuos.
(Vouchsafe me to praise thee, sacred Virgin: give to me strength against thine enemies.)
— Antiphon at Prime
In prole mater, in partu virgo, gaude et lætare, Virgo Mater Domini.
(In offspring a mother, in birthgiving a virgin, rejoice and be glad, Virgin Mother of the Lord.)
— Antiphon at Sext
Beata mater, et intacta virgo, gloriosa Regina mundi, intercede pro nobis ad Dominum.
(Blessed Mother, and intact Virgin, glorious Queen of the world, intercede for us with the Lord.)
— Antiphon at None
Post partum, Virgo, inviolata permansisti: Dei Genetrix, intercede pro nobis.
(After childbirth, O Virgin, thou didst remain inviolate: Mother of God, intercede for us.)
— Antiphon at Lauds
