Luke 15:12

The younger son then went away not yet matured in mind, and seeks from his father the part of his inheritance which fell to him, that in truth he might not serve of necessity. For we are rational animals endowed with free will.

(Esai. 3, 23.) Besides, it belongs more to the character of the aged to have an old man's mind and gravity, than his hoar hairs, nor is he blamed who is young in age, but it is the young in habits who lives according to his passions.

(ut sup.) Now the Scripture says, that the father divided equally between his two sons his substance, that is, the knowledge of good and evil, which is a true and everlasting possession to the soul that uses it well. The substance of reason which flows from God to men at their earliest birth, is given equally to all who come into this world, but after the intercourse that follows, each one is found to possess more or less of the substance; since one believing that which he has received to be from his father, preserves it as his patrimony, another abuses it as something that may be wasted away, by the liberty of his own possession. But the freedom of will is shown in that the father neither kept back the son who wished to depart, nor forced the other to go that desired to remain, lest he should seem rather the author of the evil that followed. But the youngest son went afar off, not by changing his place, but by turning aside his heart. Hence it follows, He took a journey into a far country.

The substance of man is the capacity of reason which is accompanied by free will, and in like manner whatever God has given us shall be accounted for our substance, as the heaven, the earth, and universal nature, the Law and the Prophets.

St. Luke has given three parables successively; the sheep which was lost and found, the piece of silver which was lost and found, the son who was dead and came to life again, in order that invited by a threefold remedy, we might heal our wounds. Christ as the Shepherd bears thee on His own body, the Church as the woman seeks for thee, God as the Father receives thee, the first, pity, the second, intercession, the third, reconciliation. Now you see that the Divine patrimony is given to them that seek; nor think it wrong in the father that he gave it to the younger, for no age is weak in the kingdom of God; faith is not weighed down by years. He at least counted himself sufficient who asked, And I wish he had not departed from his father, nor had had the hindrance of age.
