'Brethren and fathers, people in the world when they erect a luxurious house give themselves no rest at night and at the end of the day they toil and plan, labouring until they have achieved their object; and such is the longing that fills them that their mind is wholly occupied in this and in considering how the roof may be well-covered, how the floor, adorned with many different marbles with every other form of elegance, will offer lovers of fine sights the most pleasing appearance. But if someone were to wish to tear them away from that care, they would be most distressed, as though they were being seriously wronged. But we, when we are building not a corruptible house but an incorruptible, not one made out of stones and wood but one skilfully constructed from spiritual graces, how can we be idle and come far below these others in zeal? How should this not be the greatest of wrongs? That other house harbours people who love the flesh and when it has passed through many masters it will be pulled down and deserted. The other knows that it welcomes the Holy Spirit, since we are a temple of the living God and the Spirit of God dwells in us, as the divine Apostle says. Moreover with those who depart from things here it leaves too and abides in heaven intact and eternal. What is the material of this building? The assumption of the virtues. Take first, if you will, as a foundation stone, the fear of God, since the fear of the Lord is the beginning of wisdom. Next understanding, courage, sobriety, justice; and so with one attached firmly to the other and fitted together with the bond of love it will grow into a holy temple of the Lord, as it is written.'
