Excerpt, On Acts:

Do you see the watchful soul? With women and children and maid servants, they sang hymns to God, made purer than the sky by affliction...Nothing ever was more splendid than the Church. Let us imitate these, let us imitate them:...the Church of God rising up in the midst of the night. Do you rise up too, and behold the quire of the stars, the deep silence, the profound repose, contemplate with awe the order of your Master's household. Then your soul will be purer: it will be lighter, subtler, and soaring, disengaged: the darkness itself, the imposing silence are sufficiant to lead you to compunction...Sleep has invaded and defeated nature: it is the image of death, the image of the end of all things...Let the house be a Church, consisting of men and women...For where two, He says, are gathered together in My name, there I am in the midst of them...Where Christ is there must be Angels, and Archangels, and other Powers.

St. John Chrysostom, Homily XXVI on Acts XII, B#55.
