Luke 15:31

But the kind father was still desirous to save him, saying, Thou art ever with me, either as a Jew in the law, or as the righteous man in communion with Him. For if he ceases to envy, he will feel all things to be his, either as the Jew possessing the sacraments of the Old Testament, or as a baptized person those of the New also. Or else, This brother is described so as to be said to come from the farm, that is, engaged in worldly occupations, so ignorant of the things of the Spirit of God, as at last to complain that a kid had never been slain for him. For not for envy, but for the pardon of the world, was the Lamb sacrificed. The envious seeks a kid, the innocent a lamb, to be sacrificed for it. Therefore also is he called the elder, because a man soon grows old through envy. Therefore too he stands without, because his malice excludes him; therefore could he not hear the dancing and music, that is, not the wanton fascinations of the stage, but the harmonious song of a people, resounding with the sweet pleasantness of joy for a sinner saved. For they who seem to themselves righteous are angry when pardon is granted to one confessing his sins. Who art thou that speakest against thy Lord, that he should not, for example, forgive a fault, when thou pardonest whom thou wilt? But we ought to favour forgiving sin after repentance, lest while grudging pardon to another, we ourselves obtain it not from our Lord. Let us not envy those who return from a distant country, seeing that we ourselves also were afar off.

(ubi sup.) Or after having said, "This is boasting, not truth," the father does not agree with him, but restrains him in another way, saying, Thou art with me, by the law under which thou art bound; not as though he had not sinned, but because God continually drew him back by chastening. Nor is it wonderful that he lies to his father who hates his brother.

But the father does not rebuke him as a liar, but commending his stedfastness with him invites him to the perfection of a better and happier rejoicing. Hence it follows, But he said to him, Son, thou art ever with me. (ubi sup.) But what means he that he adds, And all that I have is thine, as if they were not his brother's also? But it is thus that all things are looked at by perfect and immortal children, that each is the possession of all, and all of each. For as desire obtains nothing without want, so charity nothing with want. But how all things? Must then God be supposed to have subjected the angels also to the possession of such a son? If you so take possession as that the possessor of a thing is its lord, certainly not all things. For we shall not be the lords, but the companions of angels. Again, if possession is thus understood, how do we rightly say that our souls possess truth? I see no reason why we may not truly and properly say so. For we do not so speak as to call our souls the mistresses of truth. Or if by the term possession we are hindered from this sense, let that also be set aside. For the father says not, "Thou possessest all things," but All that I have is thine, still not as if thou wert its lord. For that which is our property may be either food for our families, or ornament, or something of the kind. And surely, when he can rightly call his father his own, I do not see why he may not also rightly call his own what belongs to his father, only in different ways. For when we shall have obtained that blessedness, the higher things will be ours to look upon, equal things ours to have fellowship with, the lower things ours to rule. Let then the elder brother join most safely in the rejoicing.

(Hom. 64. in Matt.) But it is asked, whether one who grieves at the prosperity of others is affected by the passion of envy. We must answer, that no Saint grieves at such things; but rather looks upon the good things of others as his own. Now we must not take every thing contained in the parable literally, but bringing out the meaning which the author had in view, search for nothing farther. This parable then was written to the end that sinners should not despair of returning, knowing that they shall obtain great things. Therefore he introduces others so troubled at these good things as to be consumed with envy, but those who return, treated with such great honour as to become themselves an object of envy to others.

Which we also ourselves sometimes feel; for some live a most excellent and perfect life, another off time even in his old age is converted to God, or perhaps when just about to close his last day, through God's mercy washes away his guilt. But this mercy some men reject from restless timidity of mind, not counting upon the will of our Saviour, who rejoices in the salvation of those who are perishing.
