My fellow Christians, today is the birthday of this church, an occasion for celebration and rejoicing. We, however, ought to be the true and living temple of God. Nevertheless, Christians rightly commemorate this feast of the church, their mother, for they know that through her they were reborn in the spirit. At our first birth, we were vessels of God’s wrath; reborn, we became vessels of his mercy. Our first birth brought death to us, but our second restored us to life.
Indeed, before our baptism we were sanctuaries of the devil; but after our baptism we merited the privilege of being temples of Christ. And if we think more carefully about the meaning of our salvation, we shall realise that we are indeed living and true temples of God. God does not dwell only in things made by human hands, nor in homes of wood and stone, but rather he dwells principally in the soul made according to his own image and fashioned by his own hand. Therefore, the apostle Paul says: The temple of God is holy, and you are that temple.
