Luke 15:27

(ubi sup.) The elder son is the people of Israel, not indeed gone into a distant country, yet not in the house, but in the field, that is, in the paternal wealth of the Law and the Prophets, choosing to work earthly things. But coming from the field he began to draw nigh to the house, that is, the labour of his servile works being condemned by the same Scriptures, he was looking upon the liberty of the Church. Whence it follows; And as he came and drew nigh to the house, he heard music and dancing; that is, men filled with the Holy Spirit, with harmonious voices preaching the Gospel. It follows, And he called one of the servants, &c. that is, he takes one of the prophets to read, and as he searches in it, asks in a manner, why are those feasts celebrated in the Church at which he finds himself present? His Father's servant, the prophet, answers him. For it follows; And he said unto him, Thy brother is come, &c. As if he should say, Thy brother was in the farthest parts of the earth, but hence the greater rejoicing of those who sing a new song, because His praise is from the end of the earth; (Is. 42:10.) and for his sake who was afar off, was slain the Man who knows how to bear our infirmities, for they who have not been told of Him have seen Him. (See Isa. 53:4; 52:15.)

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.

If anyone says that the virtuous and sober son signifies Israel according to the flesh, we cannot agree to this opinion. In no way is it fitting to say that Israel chose a blameless life. Throughout the whole inspired Scripture, we see them accused of being rebels and disobedient.…I think it is right to mention this also. Some refer to the person of our Savior as that fatted calf that the father killed when his son was called to conversion.… If any one imagines that the virtuous and sober son means the physical Israel, how can Israel honestly say that he never gave him a kid? Whether we call it calf or kid, Christ is to be understood as the sacrifice offered for sin. He was not sacrificed only for the Gentiles but also that he might redeem Israel, who by reason of his frequent transgression of the law had brought great blame on himself. The wise Paul bears witness to this, saying, "For this reason Jesus also, that he might sanctify the people by his blood, suffered outside the gate."

Or to take the whole differently; the character of the son who seems to complain is put for all those who are offended at the sudden advances and salvation of the perfect, as David introduces one who took offence at the peace of sinners. Or he was in the field, that is, in the world, pampering his own flesh, that he might be filled with bread, and sowing in tears that he might reap in joy, but when he found what was being done, he was unwilling to enter into the common joy. Or by this parable our Lord reproves the will of the Pharisees, whom according to the argument he terms just, as if to say, Let it be that you are truly just, having transgressed none of the commandments, must we then for this reason refuse to admit those who turn away from their iniquities? The son then says to the father, For nothing I left a life of sorrow, ever harassed by sinners who were my enemies, and never hast thou for my sake ordered a kid to be slain, (that is, a sinner who persecuted me,) that I might enjoy myself for a little. Such a kid was Ahab to Elijah, who said, Lord, they have killed thy prophets. (1 Kings 19:14.)

Your brother has come, and your father has killed the fattened calf, because he received him safe and sound. Your brother was in the ends of the earth, but from there greater joy comes from those singing a new song to the Lord, for his …
