Clement of Alexandria

With milk, then, the Lord's nutriment, we are nursed directly we are born; and as soon as we are regenerated, we are honoured by receiving the good news of the hope of rest, even the Jerusalem above, in which it is written that milk and honey fall in showers, receiving through what is material the pledge of the sacred food. "For meats are done away with," as the apostle himself says; but this nourishment on milk leads to the heavens, rearing up citizens of heaven, and members of the angelic choirs.
