Mystical City of God Vol III
319: The most blessed Lady also asked Him for
the Sacrament of Baptism, which He had now instituted,
and which He had promised Her before. In order that
this might be administered with a dignity becoming as
well the Son as the Mother, an innumerable host
of angelic spirits descended from heaven in visible
forms. Attended by them, Christ himself baptized his
purest Mother. Immediately the voice of the eternal
Father was heard saying: "This is my beloved
Daughter, in whom I take delight." The incarnate
Word said: "This is my Mother, much beloved, whom
I have chosen and who will assist Me in all my works."
And the Holy Ghost added: "This is my Spouse,
chosen among thousands." The purest Lady felt and
received such great and numerous effects of grace in her
soul, that no human words can describe them; for She
was exalted to new heights of grace and her holy soul
was made resplendent with new and exquisite beauty
of heaven. She received the characteristic token im-
pressed by this Sacrament, namely, that of the children
of Christ in his holy Church. In addition to the ordi-
nary effects of this Sacrament (outside of the remis-
sion of sins, of which She stood in no need), She merited
especial graces on account of the humility with which
She submitted to this Sacrament of purification. By it
She accuмulated blessings like to those of her divine
Son, with only this difference: that She received an in
crease of grace, which was not possible in Christ There
upon the humble Mother broke out in a canticle of praise
with the holy angels, and prostrate before her divine
Son, She thanked Him for the most efficacious graces
She had received in this Sacrament.
