Let us then reverence the gift of peace, which Christ when He departed hence left to us. Peace both in name and reality is sweet, which also we have heard to be of God, as it is said, The peace of God; (Phil. 4:7.) and that God is of it, as He is our peace. (Eph. 2:14.) Peace is a blessing commended by all, but observed by few. What then is the cause? Perhaps the desire of dominion or riches, or the envy or hatred of our neighbour, or some one of those vices into which we see men fall who know not God. For peace is peculiarly of God, who binds all things together in one, to whom nothing so much belongs as the unity of nature, and a peaceful condition. It is borrowed indeed by angels and divine powers, which are peacefully disposed towards God and one another. It is diffused through the whole creation, whose glory is tranquillity. But in us it abides in our souls indeed by the following and imparting of the virtues, in our bodies by the harmony of our members and organs, of which the one is called beauty, the other health.
