“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.”

“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. For it follows, And not many days after, the younger son gathered all together, and took his journey into a far country.”

“(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 shewn 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.”

“(de Quæst. Ev. lib. ii. qu. 33.) But that which is said to have taken place not many days after, namely, that gathering all together he set out abroad into a far country, which is forgetfulness of God, signifies that not long after the institution of the human race, the soul of man chose of its free will to take with it a certain power of its nature, and to desert Him by whom it was created, trusting in its own strength, which it wastes the more rapidly as it has abandoned Him who gave it. Hence it follows, And there wasted his substance in riotous living. But he calls a riotous or prodigal life one that loves to spend and lavish itself with outward show, while exhausting itself within, since every one follows those things which pass on to something else, and forsakes Him who is closest to himself. As it follows, And when he had spent all, there arose a great famine in that land. The famine is the want of the word of truth. It follows, And he began to be in want. Fitly did he begin to be in want who abandoned the treasures of the wisdom and the knowledge of God, and the unfathomableness of the heavenly riches. It follows, And he went and joined himself to a citizen of that country.”

“And not many days after the younger son gathered all together , or, according to the Syriac version, “ collected together all that had come to him,” and took his journey into a far country — “ far off,” says Euthymius, “ not by local separation, but by separation in point of virtue.” Such is a state of concupiscence and sin, for the sinner by sinning goes far from God and from heaven, and subjects himself to the dominion of Satan. “ But,” says Euthymius, “ the elder son being wise, remained with his father.” Hence S. Augustine goes on to say, “The far country is forgetfulness of God, a forgetfulness which is mutual, for inasmuch as the sinner forgets God, God in His turn is in a manner forgetful of the sinner, ie. God ceases to bestow on him Hght, grace, or guidance.” Digitized by Google THE PRODIGAL’S ABANDONED LTFE. 373 For S. Jerome says, “ We must bear in mind that we are with God, or depart from Him, according to our disposition, not according to 4 distances of place.’ ” Therefore, adds Theophylact, u when a man departs from God, and from the fear of God, he wastes and consumes all God’s gifts.” And there wasted his substance , Le., all the gifts of nature and grace. For the sinner, giving himself up to pleasure and licentiousness, incurs the loss of all God’s gifts of grace. He becomes dull of understanding and is unable to recognise God, or the beauty of holiness. He grows forgetful of God’s law and God’s goodness towards him. He so corrupts his will as to prefer vice to virtue, pleasure to reason, earth to heaven, the evil one to God ; and forsaking the paths of virtue, gives himself up to every kind of evil Hence he becomes destitute of counsel, reason, sense, and everything that is good ; and at last, with all the powers of his soul and body, he worships the creature rather than the Creator, and falls into that sin to which the Psalmist refers, “So they that forsake Thee shall perish ; Thou hast destroyed all them that commit fornication against Thee.” Ps. lxxiil 26. The prodigal son “ wasted all the graces of nature,” says Euthymius, because, adds S. Augustine, “he made a wrong use of his natural gifts.” “He then,” says Titus, “expended his goods” (substantiam), ie.9 the light which was in him, temperance, the knowledge of the truth, the remembrance of God. And lastly, says Euthymius again, “he corrupted the gift which he had received at his baptism, i.e. nobility of soul, and the capability of living a godly life, for such things as these made up the riches of the prodigal With riotous living , By living an abandoned life (d*<£r«;), not only sinful but also luxurious and intemperate. “ A prodigal life,” says the Gloss, “ loves to occupy itself in outward show, forgetful of God, who has His dwelling within.””

“And not many days after the younger son gathered all together,.... That his father had divided to him, all his goods and substance: as soon as a man has any internal substance, any considerable degree of natural knowledge, he immediately sets out from God, and employs it against him, in reasoning against him, against his being, his works, his providence, his purposes, his revelation, and will; as soon as a man has the exercise of his reason, as soon as he can think and speak, nay, as soon as he is born, he goes astray from God, speaking lies; and as soon as a wicked man has of this world, what his carnal heart desires, he is for living independent of God, and his providence; he is for gathering together all for himself, in order to spend it on his lusts, and at a distance from his father, the father of his mercies, of whom he is not mindful; and to whom he says, depart from me, having no regard to his worship and service, to his honour and glory, to his cause and interest: and took his journey into a far country; which sets forth the state of alienation a sinner is in, while unconverted; he is afar off from God, from God the Father; from the presence of God, and communion with him: from the knowledge of God, and desire after it; from love to him, or fear of him; and from the life of God, or a living soberly, righteously, and godly; and from Christ, from the knowledge of him, from faith in him, love to him, fellowship with him, and subjection to his ordinances; and from the Spirit of God, and every thing that is spiritual; and from all that is good, from the law of God, and from the righteousness of it, and from righteous men: and there wasted his substance in riotous living; his internal substance, his knowledge and understanding, even in natural things, and became brutish, and even like the beasts that perish; and his worldly substance in rioting and drunkenness, in chambering and wantonness, with harlots, as in Luk 15:30 whereby he was brought to a piece of bread, and to the want of it,”

“Not many days after - He probably hastened his departure for fear of the fine which he must have paid, and the reproach to which he must have been subjected, had the matter come before the civil magistrate. See above. Riotous living - Ζων ασωτως, in a course of life that led him to spend all: from α not, and σωω I save. And this we are informed, Luk 15:30, was among harlots; the readiest way in the world to exhaust the body, debase the mind, ruin the soul, and destroy the substance.”

“not many days--intoxicated with his new--found resources, and eager for the luxury of using them at Will. a far country--beyond all danger of interference from home. wasted, &c.--So long as it lasted, the inward monitor (Isa 55:2) would be silenced (Isa 9:10; Isa 57:10; Amo 4:6-10). riotous living-- (Luk 15:30), "with harlots." Ah! but this reaches farther than the sensualist; for "in the deep symbolical language of Scripture fornication is the standing image of idolatry; they are in fact ever spoken of as one and the same sin, considered now in its fleshly, now in its spiritual aspect" (Jer 3:1-15; Eze. 16:1-17:24) [TRENCH].”
