Catena Aurea · Lukasevangelium 24
And as they thus spake, Jesus himself stood in the midst of them, and saith unto them, Peace be unto you. But they were terrified and affrighted, and supposed they had seen a spirit. And he said unto them, Why are ye troubled? and why do thoughts arise in your hearts? Behold my hands and my feet, that it is I myself: handle me, and see; for a spirit hath not flesh and bones, as ye see me have. And when he had thus spoken, he shewed them his hands and feet. But let us see what mystery it was for the sake of which, according to Matthew and Mark, our Lord when He rose again gave the following command, I will go before you into Galilee, there shall ye see me. Which although it was accomplished, yet it was not till after many other things had happened, whereas it was so commanded, that it might be expected that it would have taken place alone, or at least before other things.
(Orat. 22.) 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.
