Matthew 23:27,28

Ver 27. "Woe unto you, Scribes and Pharisees, hypocrites! for ye are like unto whited sepulchres, which indeed appear beautiful outward, but are within full of dead men's bones, and of all uncleanness. 28. Even so ye also outwardly appear righteous unto men, but within ye are full of hypocrisy and iniquity."

Origen: As above they are said to be "full of extortion and excess," so here they are "full of hypocrisy and iniquity," and are likened to dead men's bones, and all uncleanness.

Pseudo-Chrys.: 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.

Jerome: Sepulchres are whitened with lime without, and decorated with marble painted in gold and various colours, but within are full of dead men's bones. Thus crooked teachers who teach one thing and do another, affect purity in their dress, and humility in their speech, but within are full of all uncleanness, covetousness, and lust.

Origen: For all feigned righteousness is dead, forasmuch as it is not done for God's sake; yea, rather it is no righteousness at all, any more than a dead man is a man, or an actor who represents any character is the man whom he represents. There is therefore within them so much of bones and uncleanness as are the good things that they wickedly pretend to. And they seem righteous outwardly, not in the eyes of such as the Scripture calls "Gods," but of such only as "die like men." [Psalms 82:6]

Greg., Mor., xxvi, 32: But before their strict Judge they cannot have the plea of ignorance, for by assuming in the eyes of men every form of sanctity, they witness against themselves that they are not ignorant how to live well.

Pseudo-Chrys.: 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.
