The Expectation of the Blessed Virgin Mary

The lovely little music book, The Story of the Redemption for Children, contains a song to commemorate the Annunciation on this the second day we celebrate the Incarnation of Our Lord during the year.

The collect for the day is:

O God who didst will that Thy Word should,
by the message of an Angel,
take flesh in the womb of the Blessed Virgin Mary,
grant unto us, we beseech Thee,
that all we who do believe her to be in very deed
the Mother of God,
may be holpen by her prayers in Thy sight.
O maiden of maidens,
how shall this be,
since neither before nor henceforth hath there been,
nor shall be such another?
Daughters of Jerusalem,
why look ye curiously upon me?
What ye see is a mystery of God.

And to commemorate her perpetual virginity:

Gaude Maria, Virgo, cunctas haereses sola interemisti:

Rejoice, O Mary,
by whose mighty hand the Church hath victory
over her foes [every heresy] achieved,
since thou to Gabriel's word of quickening power
in lowliness hast listened, and believed
-- thou, still a virgin, in thy blessed womb
hast God Incarnate of thy flesh conceived,
and still, in heaven, of that virginity remainest
after childbirth unbereaved.
V. Blessed art thou that hast believed,
for there is a performance of those things
which were told thee from the Lord.
