Romans 15:16

The Gentiles are offered to God as an acceptable sacrifice when they believe in Christ and are sanctified through the gospel.

And we, who through the name of Jesus have believed as one man in God the Maker of all, have been stripped, through the name of His first-begotten Son, of the filthy garments, i.e., of our sins; and being vehemently inflamed by the word of His calling, we are the true high priestly race of God, as even God Himself bears witness, saying that in every place among the Gentiles sacrifices are presented to Him well-pleasing and pure. Now God receives sacrifices from no one, except through His priests.

I beg also that there may be no lack, on your parts, of wisdom and carefulness to preserve peace. For although from their affection the brethren are eager to approach and to visit those good confessors, on whom by their glorious beginnings the divine consideration has already shed a brightness, yet I think that this eagerness must be cautiously indulged, and not in crowds,-not in numbers collected together at once', lest from this very thing ill-will be aroused, and the means of access be denied, and thus, while we insatiably wish for all, we lose all. Take counsel, therefore, and see that this may be more safely managed with moderation, so that the presbyters also, who there offer with the confessors, may one by one take turns with the deacons individually; because, by thus changing the persons and varying the people that come together, suspicion is diminished. For, meek and humble in all things, as befits the servants of God, we ought to accommodate ourselves to the times, and to provide for quietness, and to have regard to the people. I bid you, brethren, beloved and dearly longed-for, always heartily farewell; and have me in remembrance. Greet all the brotherhood. Victor the deacon, and those who are with me, greet you.

For this reason the divine rebuke does not cease to chastise us night nor day. For besides the visions of the night, by day also, the innocent age of boys is among us filled with the Holy Spirit, seeing in an ecstasy with their eyes, and hearing and speaking those things whereby the Lord condescends to warn and instruct us. And you shall hear all things when the Lord, who bade me withdraw, shall bring me back again to you. In the meanwhile, let those certain ones among you who are rash and incautious and boastful, and who do not regard man, at least fear God, knowing that, if they shall persevere still in the same course, I shall use that power of admonition which the Lord bids me use; so that they may meanwhile be withheld from offering, and have to plead their cause both before me and before the confessors themselves and before the whole people, when, with God's permission, we begin to be gathered together once more into the bosom of the Church, our Mother. Concerning this matter, I have written to the martyrs and confessors, and to the people, letters; both of which I have bidden to be read to you. I wish you, dearly beloved brethren and earnestly longed-for, ever heartily farewell in the Lord; and have me in remembrance.

"That I should be the minister of Jesus Christ to the Gentiles, ministering the Gospel of God." For after his abundant proof of his statements, he draws his discourse to a more lofty tone, not speaking of mere service, as in the beginning, but of service and priestly ministering. For to me this is a priesthood, this preaching and declaring. This is the sacrifice I bring. Now no one will find fault with a priest, for being anxious to offer the sacrifice without blemish. And he says this at once to elevate their thoughts, and show them that they are a sacrifice, and in apology for his own part in the matter, because he was appointed to this office. For my knife, he says, is the Gospel, the word of the preaching. And the cause is not that I may be glorified, not that I may appear conspicuous, but that the "offering up of the Gentiles may be acceptable, being sanctified by the Holy Ghost." That is, that the souls of those that are taught by me, may be accepted. For it was not so much to honor me, that God led me to this pitch, as out of a concern for you. And how are they to become acceptable? In the Holy Spirit. For there is need not only of faith, but also of a spiritual way of life, that we may keep the Spirit that was given once for all. For it is not wood and fire, nor altar and knife, but the Spirit that is all in us. For this cause, I take all means to prevent that Fire from being extinguished, as I have been also enjoined to do. Why then do you speak to those that need it not? This is just the reason why I do not teach you, but put you in mind, he replies. As the priest stands by stirring up the fire, so I do, rousing up your ready-mindedness. And observe, he does not say, "that the offering up of" you "may be" etc. […]
