Lk. 15:23. Bring the fatted calf and kill it, and let us eat and be merry!
Who is the "fatted... calf," slain and eaten, is not difficult to understand. He is, without doubt, the true Son of God. Since He is Man and took upon Himself flesh, by nature irrational and beast-like, though He filled it with His own perfections, He is therefore called the Calf. This Calf did not experience the yoke of the law of sin, but is a "fatted" Calf, since He was foreordained for this Mystery "before the foundation of the world" (1 Pet. 1:20). Perhaps what remains to be said will seem far-fetched, but let it be said nonetheless. The Bread which we break, in its outward form consists of wheat, and therefore may be called fattened with wheat, while on the spiritual side it is Flesh, and therefore may be called a Calf, and thus One and the Same is both the Calf and the fatted one.
Lk. 15:24. For this my son was dead and is alive again, was lost and is found. And they began to be merry.
So then, everyone who repents and becomes a son of God, and especially one who is restored and generally cleansed from sin, partakes of this fatted Calf and becomes a cause of joy for the Father and His servants, the Angels and priests: "For he was dead and is alive again, was lost and is found." In the sense that he remains in evil, he "was dead," that is, without hope, but in the sense that human nature is easily inclined and can turn from wickedness to virtue, he is called "lost." For the word "lost" is milder than "dead."
Lk. 15:25. The elder son was in the field; and as he was returning, when he drew near to the house, he heard music and dancing;
Lk. 15:26. And he called one of the servants, and asked what these things meant.
Lk. 15:27. He said to him: your brother has come, and your father has killed the fatted calf, because he has received him back in good health.
Lk. 15:28. He became angry and did not want to go in. But his father, coming out, called him.
Lk. 15:29. But he answered and said to his father: Behold, I have served you so many years and never transgressed your commandment, yet you never gave me even a young goat, that I might make merry with my friends;
Lk. 15:30. But when this son of yours, who has squandered his property with harlots, came, you killed the fatted calf for him.
Lk. 15:31. Son, you are always with me, and all that is mine is yours.
Lk. 15:32. But it was right to be glad and to rejoice, for this your brother was dead and is alive again, was lost and is found.
Here they raise the well-known question: how is it that the son who in all other respects lived and served his father in a pleasing manner turns out to be envious? But the question will be resolved as soon as one considers why this parable was told. This parable, together with the preceding ones, was told, without doubt, because the Pharisees, who considered themselves pure and righteous, murmured against the Lord for receiving harlots and tax collectors. And if it was told because the Pharisees murmured — they who appeared to be more righteous than the tax collectors — then observe that the figure of the son who appears to murmur applies to all who are scandalized by the sudden good fortune and salvation of sinners. And this is not envy, but rather the outpouring of God's love for mankind, which is incomprehensible to us, and therefore gives rise to murmuring. Does not David also present people who are scandalized by the peace of sinners (Ps. 73:3)? Likewise Jeremiah, when he says: "Why does the way of the wicked prosper?" "You have planted them, and they have taken root" (Jer. 12:1–2). All this is characteristic of the weak and poor human mind, which is troubled and perplexed at the sight of unworthiness — namely, the prosperity of wicked people. Therefore the Lord, through the present parable, speaks as it were thus to the Pharisees: granted that you, like this son, are righteous and pleasing before the Father; but I ask you, righteous and pure as you are, not to murmur that we prepare a feast for the salvation of a sinner, for he too is a son. Thus what is revealed here is not envy, but by this parable the Lord instructs the Pharisees not to be vexed at the reception of sinners, even if they themselves are righteous and keep every commandment of God. And it is not at all surprising if we are grieved at the reception of those who seem unworthy. The love of God for mankind is so great and so abundantly bestows its blessings upon us that even murmuring can arise from it. So too we speak in ordinary conversation. Often, having done someone a kindness and then receiving no gratitude from him, we say: everyone reproaches me for having bestowed so many benefits upon you. Although perhaps no one has reproached us at all, wishing to show the greatness of the kindness, we invent this.
Let us examine this parable part by part and, as it were, in a brief summary. "The elder son was in the field," that is, in this world, tilling his land, that is, the flesh, so that it might abound in bread, and sowing with tears so as to reap with joy (Ps. 125:5). Having learned of what had happened, he did not want to enter into the common joy. But the compassionate Father comes out, calls him, and informs him that the cause of the celebration is the revival of one who was dead — something the son did not know, being a man who takes offense and accuses the Father for not having given him "even a young goat," while for the profligate He slaughtered the fattened calf. What is signified by the "young goat"? You can learn from the fact that every goat is assigned to the left side, the side of sinners (Matt. 25:33, 41). So the virtuous son says to the Father: I spent my life in every kind of toil, endured persecutions, troubles, and insults from sinners, and You never slaughtered or killed a young goat for me — that is, a sinner who offended me — so that I might find a little pleasure. For example, Ahab was a goat in relation to Elijah. He persecuted the prophet, but the Lord did not immediately deliver this goat to slaughter so as to bring some small joy to Elijah and give rest to him along with his friends the prophets. Therefore Elijah says to God: "They have torn down Your altars and killed Your prophets" (1 Kings 19:14). In relation to David, the goat was Saul and all who slandered him, whom the Lord allowed to tempt him but did not kill for David's pleasure. Therefore David says: "How long, O Lord, shall the wicked, how long shall the wicked triumph?" (Ps. 94:3). So also this son presented in the Gospel says: the one who labors constantly, him You did not deem worthy of any consolation, nor did You even deliver to slaughter any of those who offended me, yet now, without any effort, You save the profligate! Thus the entire purpose of this parable, told on account of the Pharisees' grumbling against the Lord for His reception of sinners, is to teach us not to reject sinners and not to grumble when God receives them, even if we ourselves are righteous. The younger son represents the harlots and tax collectors; the elder son represents the Pharisees and scribes, who are supposedly regarded as righteous. God says, as it were: granted that you are indeed righteous and have transgressed no commandment, but surely those who turn from evil ought to be received? It is murmurers such as these that the Lord instructs through the present parable.
It is not unknown to me that some understood the elder son as referring to Angels, and the younger to human nature, which rebelled and did not submit to the given commandment. Others understood the elder as the Israelites, and the younger as the Gentiles. But what we have just said is true, namely: that the elder son represents the person of the righteous, and the younger that of sinners and the repentant, and the entire construction of the parable was composed on account of the Pharisees, whom the Lord impresses upon that they, even if they themselves were righteous, should not be grieved by the acceptance of sinners. Therefore, let no one take offense at the judgments of God, but let him be patient even in the case when sinners, it would seem, are made prosperous and are saved. For how do you know? Perhaps the one whom you consider a sinner has offered repentance, and for that reason has been accepted. And it may also be that he has secret virtues, and on account of them is favorable in the eyes of God.
