1 Peter 3:20

These things, beloved, we write unto you, not merely to admonish you of your duty, but also to remind ourselves. For we are struggling on the same arena, and the same conflict is assigned to both of us. Wherefore let us give up vain and fruitless cares, and approach to the glorious and venerable rule of our holy calling. Let us attend to what is good, pleasing, and acceptable in the sight of Him who formed us. Let us look stedfastly to the blood of Christ, and see how precious that blood is to God, which, having been shed for our salvation, has set the grace of repentance before the whole world. Let us turn to every age that has passed, and learn that, from generation to generation, the Lord has granted a place of repentance to all such as would be converted unto Him. Noah preached repentance, and as many as listened to him were saved. …

3. Further, they declare that the arrangement made with respect to the ark in the Deluge, by means of which eight persons were saved, most clearly indicates the Ogdoad which brings salvation. David also shows forth the same, as holding the eighth place in point of age among his brethren. Moreover, that circumcision which took place on the eighth day, represented the circumcision of the Ogdoad above. In a word, whatever they find in the Scriptures capable of being referred to the number eight , they declare to fulfil the mystery of the Ogdoad. With respect, again, to the Decad, they maintain that it is indicated by those ten nations which God promised to Abraham for a possession. The arrangement also made by Sarah when, after ten years, she gave her handmaid Hagar to him, that by her he might have a son, showed the same thing. …

2. It was for this reason, too, that the Lord descended into the regions beneath the earth, preaching His advent there also, and [declaring] the remission of sins received by those who believe in Him. Now all those believed in Him who had hope towards Him, that is, those who proclaimed His advent, and submitted to His dispensations, the righteous men, the prophets, and the patriarchs, to whom He remitted sins in the same way as He did to us, which sins we should not lay to their charge, if we would not despise the grace of God. For as these men did not impute unto us (the Gentiles) our transgressions, which we wrought before Christ was manifested among us, so also it is not right that we should lay blame upon those who sinned before Christ’s coming. …

But how? Do not [the Scriptures] show that the Lord preached the Gospel to those that perished in the flood, or rather had been chained, and to those kept “in ward and guard”? And it has been shown also, in the second book of the Stromata , that the apostles, following the Lord, preached the Gospel to those in Hades. For it was requisite, in my opinion, that as here, so also there, the best of the disciples should be imitators of the Master; so that He should bring to repentance those belonging to the Hebrews, and they the Gentiles; that is, those who had lived in righteousness according to the Law and Philosophy, who had ended life not perfectly, but sinfully. …

“Coming,” he says, “He preached to those who were once unbelieving.” They saw not His form, but they heard His voice.

But, again, the heresy has started forth which is called that of the Sethites . The doctrine of this perversity is as follows. Two human beings were formed by the angels, Cain and Abel. On their account arose great contentions and discords among the angels; for this reason, that Virtue which was above all the Virtues, which they style the Mother, when they said that Abel had been slain, willed this Seth of theirs to be conceived and born in place of Abel, in order that those angels might be escheated who had created those two former human beings, while this pure seed rises and is born. …

3. And now, what we have drawn from the authority of Scripture ought to be sufficient to refute the arguments of the heretics. It will not, however, appear improper if we discuss the matter with them shortly, on the grounds of reason itself. We ask them, then, if they know what is regarded among men as the ground of virtue and wickedness, and if it appears to follow that we can speak of virtues in God, or, as they think, in these two Gods. Let them give an answer also to the question, whether they consider goodness to be a virtue; and as they will undoubtedly admit it to be so, what will they say of injustice? They will never certainly, in my opinion, be so foolish as to deny that justice is a virtue. Accordingly, if virtue is a blessing, and justice is a virtue, then without doubt justice is goodness. …

11. For it has been delivered to us, that there is one God, and one Christ, and one hope, and one faith, and one Church, and one baptism ordained only in the one Church, from which unity whosoever will depart must needs be found with heretics; and while he upholds them against the Church, he impugns the sacrament of the divine tradition. The sacrament of which unity we see expressed also in the Canticles, in the person of Christ, who says, “A garden enclosed is my sister, my spouse, a fountain sealed, a well of living water, a garden with the fruit of apples.” But if His Church is a garden enclosed, and a fountain sealed, how can he who is not in the Church enter into the same garden, or drink from its fountain? Moreover, Peter himself, showing and vindicating the unity, has commanded and warned us that we cannot be saved, except by the one only baptism of one Church. …

2. But that the Church is one, the Holy Spirit declares in the Song of Songs, saying, in the person of Christ, “My dove, my undefiled, is one; she is the only one of her mother, she is the choice one of her that bare her.” Concerning which also He says again, “A garden enclosed is my sister, my spouse; a spring sealed up, a well of living water.” But if the spouse of Christ, which is the Church, is a garden enclosed; a thing that is closed up cannot lie open to strangers and profane persons. And if it is a fountain sealed, he who, being placed without has no access to the spring, can neither drink thence nor be sealed. And the well also of living water, if it is one and the same within, he who is placed without cannot be quickened and sanctified from that water of which it is only granted to those who are within to make any use, or to drink. …

Yet of Thy goodness Thou didst not overlook him, nor suffer him to perish utterly, for he was Thy creature; but Thou didst subject the whole creation to him, and didst grant him liberty to procure himself food by his own sweat and labours, whilst Thou didst cause all the fruits of the earth to spring up, to grow, and to ripen. But when Thou hadst laid him asleep for a while, Thou didst with an oath call him to a restoration again, didst loose the bond of death, and promise him life after the resurrection. And not this only; but when Thou hadst increased his posterity to an innumerable multitude, those that continued with Thee Thou didst glorify, and those who did apostatize from Thee Thou didst punish. And while Thou didst accept of the sacrifice of Abel as of an holy person, Thou didst reject the gift of Cain , the murderer of his brother, as of an abhorred wretch. …

Now let us consider what is stated by Mark. Mark’s account of John’s preaching agrees with the other. The words are, “There cometh after me He that is mightier than I,” which amounts to the same thing as “He that cometh after me is mightier than I.” There is a difference, however, in what follows, “The latchets of His shoes I am not worthy to stoop down and untie.” For it is one thing to bear a person’s shoes, they must, it is evident, have been untied already from the feet of the wearer, and it is another thing to stoop down and untie the latchet of his shoes. And it follows, since believers cannot think that either of the Evangelists made any mistake or misrepresentation, that the Baptist must have made these two utterances at different times and have meant them to express different things. It is not the case, as some suppose. …
