Ambrose of Milan

The soul has wings by which it can raise itself free from the earth. But this movement of the wings is not of something constructed of feathers but a continuing series of good works, like those of the Lord of whom it is well said, "And in the shadow of your wings I shall take refuge." In the first place, the hands of our Lord fixed on the cross were extended like something in flight, and, second, the actions of God are like a refreshing shadow of eternal salvation that can regulate the conflagration raging in our world.
