John 1:12

"As many as received Him, to them gave He power to become sons of God." Whether bond or free, whether Greeks or barbarians or Scythians, unlearned or learned, female or male, children or old men, in honor or dishonor, rich or poor, rulers or private persons, all, He saith, are deemed worthy the same privilege; for faith and the grace of the Spirit, removing the inequality caused by worldly things, hath moulded all to one fashion, and stamped them with one impress, the King's. What can equal this lovingkindness? A king, who is framed of the same clay with us, does not deign to enrol among the royal host his fellow-servants, who share the same nature with himself, and in character often are better than he, if they chance to be slaves; but the Only-Begotten Son of God did not disdain to reckon among the company of His children both publicans, sorcerers, and slaves, nay, men of less repute and greater poverty than these, maimed in body, and suffering from ten thousand ills. Such is the power of faith in Him, such the excess of His grace.

And as the element of fire, when it meets with ore from the mine, straightway of earth makes it gold, even so and much more Baptism makes those who are washed to be of gold instead of clay; the Spirit at that time falling like fire into our souls, burning up the "image of the earthy" (1 Cor. xv. 49), and producing "the image of the heavenly," fresh coined, bright and glittering, as from the furnace-mould.

Why then did he say not that "He made them sons of God," but that "He gave them power to become sons of God"? To show that we need much zeal to keep the image of sonship impressed on us at Baptism, all through without spot or soils; and at the same time to show that no one shall be able to take this power from us, unless we are the first to deprive ourselves of it. For if among men, those who have received the absolute control of any matters have well-nigh as much power as those who gave them the charge; much more shall we, who have obtained such honor from God, be, if we do nothing unworthy of this power, greater and better than all. At the same time too he wishes to show, that not even does grace come upon man irrespectively, but upon those who desire and take pains for it. For it lies in the power of these to become (His) children since if they do not themselves first make the choice, the gift does not come upon them, nor have any effect.

Having therefore everywhere excluded compulsion and pointing to (man's) voluntary choice and free power, he has said the same now. For even in these mystical blessings, it is, on the one hand, God's part, to give the grace, on the other, man's to supply faith; and in after time there needs for what remains much earnestness. In order to preserve our purity, it is not sufficient for us merely to have been baptized and to have believed, but we must if we will continually enjoy this brightness, display a life worthy of it. This then is God's work in us. To have been born the mystical Birth, and to have been cleansed from all our former sins, comes from Baptism; but to remain for the future pure, never again after this to admit any stain belongs to our own power and diligence.

But John adds: "As many as received Him." What did He afford to them? Great benevolence! Great mercy! He was born the only Son of God, and was unwilling to remain alone. Many men, when they have not sons, in advanced age adopt a son, and thus obtain by an exercise of will what nature has denied to them: this men do. But if any one have an only son, he rejoices the more in him; because he alone will possess everything, and he will not have any one to divide with him the inheritance, so that he should be poorer. Not so God: that same only Son whom He had begotten, and by whom He created all things, He sent into this world that He might not be alone, but might have adopted brethren. For we were not born of God in the manner in which the Only-begotten was born of Him, but were adopted by His grace. For He, the Only-begotten, came to loose the sins in which we were entangled, and whose burden hindered our adoption: those whom He wished to make brethren to Himself, He Himself loosed, and made joint-heirs. For so saith the apostle, "But if a son, then an heir through God." And again, "Heirs of God, and joint-heirs with Christ." He did not fear to have joint-heirs, because His heritage does not become narrow if many are possessors. Those very persons, He being possessor, become His inheritance, and He in turn becomes their inheritance. Hear in what manner they become His inheritance: "The Lord hath said unto me, Thou art my Son, this day have I begotten Thee. Ask of me, and I will give Thee the nations for Thine inheritance." Hear in what manner He becomes their inheritance. He says in the Psalms: "The Lord is the portion of mine inheritance, and of my cup." Let us possess Him, and let Him possess us: let Him possess us as Lord; let us possess Him as salvation, let us possess Him as light. What then did He give to them who received Him? "To them He gave power to become sons of God, even to them that believe on His name;" that they may cling to the wood and cross the sea.
