John Chrysostom
Justly are the bodies of the righteous said to be temples, because in the body of the righteous the soul has dominion, as God in His temple; or because God Himself dwells in righteous bodies. But the bodies of sinners are called sepulchres of the dead, because the sinner’s soul is dead in his body; for that cannot be deemed to be alive, which does no spiritual or living act.
But say, hypocrite, if it be good to be wicked, why do you not desire to seem that which you desire to be? For what it is shameful to seem, that it is more shameful to be; and what to seem is fair, that it is fairer to be. Either therefore be what you seem, or seem what you are.
