See how continually he puts the word “called,” saying, “called to be an Apostle; among whom you also are called; to all that be in Rome, called:” and this he does not out of superfluity of words, but out of a wish to remind them of the benefit. For since among them which believed, it was likely that there would be some of the consuls (ὑ πάτων; Ben. consulares) and rulers as well as poor and common men, casting aside the inequality of ranks, he writes to them all under one appellation. But if in things which are more needful and which are spiritual, all things are set forth as common both to slaves and to free, for instance, the love from God, the calling, the Gospel, the adoption, the grace, the peace, the sanctification, all things else, how could it be other than the uttermost folly, whom God had joined together, and made to be of equal honor in the greater things, those to divide on account of things on earth? On this ground, I presume, from the very outstart, this blessed Apostle, after casting out this mischievous disease, conducts them to the mother of blessings, humble-mindedness. This made servants better, since they learned that they should take no harm from their servitude, while they had the true freedom; this would incline masters to be gentle, as being instructed that they have no advantage in being free, unless the goods of faith have the first place given them. And that you may learn that he was not doing this to work confusion, by dashing all things, but still knew the best distinction, he wrote not simply to all that were in Rome, but with a definition added, “beloved of God.” For this is the best discrimination, and shows whence the sanctification was. Whence then was the sanctification? From Love. For after saying, “beloved,” then he proceeds, “called to be saints,” showing that it is from this that the fount of all blessings is. But saints he calls all the faithful. “Grace unto you and peace.”
Oh address, that brings countless blessings to us! This also Christ bade the Apostles to use as their first word when entering into houses. Wherefore it is from this that Paul also in all places takes his beginning, from grace and peace; for it was no small war which Christ put an end to, but indeed one varying and of every kind and of a long season (τοικίλον καὶ ταντοδαπὸν); and this not from our labors, but through His grace. Since then love presented us with grace, and grace with peace, having set them down in the due order of an address, he prays over them that they may abide perpetual and unmoved, so that no other war may again be blown into flame, and beseeches Him that gave, to keep these things firmly settled, saying as follows, “Grace be unto you and peace from God our Father, and the Lord Jesus Christ.” See in this passage, the “from” is common to the Son and the Father, and this is equivalent to “of whom.” For he did not say, Grace be unto you and peace from God the Father, “through” our Lord Jesus Christ; but, “from God the Father, and the Lord Jesus Christ.” Strange! How mighty is the love of God! We which were enemies and disgraced, have all at once become saints and sons. For when he calls Him Father, he shows them to be sons; and when he says sons, he has unveiled the whole treasure of blessings.
Let us then keep showing a conversation worthy of the gift, and hold on in peace and holiness. For other dignities are but for a time, and are brought to an end along with this life present, and may be bought with money (whence one might say they are not dignities at all but names of dignities only, having their strength in the investiture of fine array and the servility of attendants), but this as having been given of God, the gift of sanctification and adoption, is not broken through even by death, but even here makes men conspicuous, and also departs with us upon our journey to the life to come. For he that holds on in the adoption, and keeps an exact watch upon his holiness, is much brighter and more happy even than he that is arrayed with the diadem itself, and has the purple; and has the delight of abundant peace in the present life and is nurtured up with goodly hopes, and has no ground for worry and disturbance, but enjoys constant pleasure; for as for good spirits and joy, it is not greatness of power, not abundance of wealth, not pomp of authority, not strength of body, not sumptuousness of the table, not the adorning of dresses, nor any other of the things in man's reach that ordinarily produces them, but spiritual success, and a good conscience alone. And he that has this cleansed, even though he be clad in rags and struggling with famine, is of better spirits than they that live so softly. So too he that is conscious of wicked deeds, even though he may gather to himself all men's goods, is the most wretched of all men. For this cause Paul, living in continual hunger and nakedness, and being scourged every day was joyful, and went more softly than they that were then emperors. But Ahab though a king, and indulging in a sumptuous luxury, when he had done that one sin, groaned and was out of spirits, and his countenance was fallen both before the sin and after the sin. If then we wish to enjoy pleasure, above all things else let us shun wickedness, and follow after virtue; since it is not in the nature of things for one to have a share thereof on any other terms, even if we were mounted upon the king's throne itself. Wherefore also Paul says, “But the fruit of the Spirit is love, joy, peace.” This fruit then let us keep growing by us, that we may be in the fruition of joy here, and may obtain the kingdom to come, by the grace and love towards man of our Lord Jesus Christ, through Whom and with Whom, be glory to the Father, and to the Holy Spirit, now and always, even unto all ages. Amen.
