The Banquet of the Ten Virgins

Now the statement that she stands upon the moon, as I consider, denotes the faith of those who are cleansed from corruption in the laver of regeneration, because the light of the moon has more resemblance to tepid water, and all moist substance is dependent upon her. The Church, then, stands upon our faith and adoption, under the figure of the moon, until the fullness of the nations come in, labouring and bringing forth natural men as spiritual men; for which reason too she is a mother.

For just as a woman receiving tim unformed seed of a man, within a certain time brings forth a perfect man, in the same way, one should say, does the Church conceive those who flee to the Word, and, forming them according to the likeness and form of Christ, after a certain time produce them as citizens of that blessed state. Whence it is necessary that she should stand upon the laver, bringing forth those who are washed in it. And in this way the power which she has in connection with the laver is called the moon, because the regenerate shine being renewed with a new ray, that is, a new light.

Whence, also, they are by a descriptive term called newly-enlightened; the moon ever showing forth anew to them the spiritual full moon, namely, the period and the memorial of the passion, until the glory and the perfect light of the great day arise.
