Macarius Chrysocephalus: Parable of the Prodigal Son, Luke xv., Oration on Luke xv., Towards the Close.
5 The parable exhibits this thought, that the exercise of the faculty of reason has been accorded to each man. Wherefore the prodigal is introduced, demanding from his father his portion, that is, of the state of mind, endowed by reason. For the possession of reason is granted to all, in order to the pursuit of what is good, and the avoidance of what is bad. But many who are furnished by God with this make a bad use of the knowledge that has been given them, and land in the profligacy of evil practices, and wickedly waste the substance of reason,— the eye on disgraceful sights, the tongue on blasphemous words, the smell on fœtid licentious excesses of pleasures, the mouth on swinish gluttony, the hands on thefts, the feet on running into plots, the thoughts on impious counsels, the inclinations on indulgence on the love of ease, the mind on brutish pastime. They preserve nothing of the substance of reason unsquandered. Such an one, therefore, Christ represents in the parable—as a rational creature, with his reason darkened, and asking from the Divine Being what is suitable to reason; then as obtaining from God, and making a wicked use of what had been given, and especially of the benefits of baptism, which had been vouchsafed to him; whence also He calls him a prodigal; and then, after the dissipation of what had been given him, and again his restoration by repentance, [He represents] the love of God shown to him.
6. For He says, “Bring hither the fatted calf, kill it, and let us eat and be merry; for this my son”— a name of nearest relationship, and significative of what is given to the faithful— “was dead and lost,”— an expression of extremest alienation; for what is more alien to the living than the lost and dead? For neither can be possessed any more. But having from the nearest relationship fallen to extremest alienation, again by repentance he returned to near relationship. For it is said, “Put on him the best robe,” which was his the moment he obtained baptism. I mean the glory of baptism, the remission of sins, and the communication of the other blessings, which he obtained immediately he had touched the font.
“And put a ring on his hand.” Here is the mystery of the Trinity; which is the seal impressed on those who believe.
“And put shoes on his feet,” for “the preparation of the Gospel of peace,” and the whole course that leads to good actions.
7. But whom Christ finds lost, after sin committed since baptism, those Novatus, enemy of God, resigns to destruction. Do not let us then reckon any fault if we repent; guarding against falling, let us, if we have fallen, retrace our steps. And while dreading to offend, let us, after offending, avoid despair, and be eager to be confirmed; and on sinking, let us haste to rise up again. Let us obey the Lord, who calls to us, “Come unto Me, all you that labour, and I will give you rest.” Let us employ the gift of reason for actions of prudence. Let us learn now abstinence from what is wicked, that we may not be forced to learn in the future. Let us employ life as a training school for what is good; and let us be roused to the hatred of sin. Let us bear about a deep love for the Creator; let us cleave to Him with our whole heart; let us not wickedly waste the substance of reason, like the prodigal. Let us obtain the joy laid up, in which Paul exulting, exclaimed, “Who shall separate us from the love of Christ?” To Him belongs glory and honour, with the Father and the Holy Spirit, world without end. Amen.
