Blood of Christ

For to this end the Lord endured to deliver up His flesh to corruption, that we might be sanctified through the remission of sins, which is effected by His blood of sprinkling. For it is written concerning Him, partly with reference to Israel, and partly to us; and [the Scripture] said thus: “He was wounded for our transgressions, and braised for our iniquities: with His stripes we are healed. He was brought as a sheep to the slaughter, and as a lamb which is dumb before its shearer.” Barnabas (A.D. 70-130) ch.5

Let us look steadfastly 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. Clement of Rome (A.D. 96) ch.7

…being imitators of God, and having your hearts kindled in the blood of God, you have perfectly fulfilled your congenial work. Ignatius: to the Ephesians (A.D. 35-105) ch.1

Jesus Christ… unto whom all things were made subject that are in heaven and that are on the earth; to whom every creature that has breath does service; who comes as judge of quick and dead; whose blood God will require of them that are disobedient unto Him. Polycarp (A.D. 69-156) ch. 2

And that expression which was committed to writing by Moses, and prophesied by the patriarch Jacob, namely, ‘He shall wash His garments with wine, and His vesture with the blood of the grape,’ signified that He would wash those that believe in Him with His own blood. For the Holy Spirit called those who receive remission of sins through Him, His garments; amongst whom He is always present in power, but will be manifestly present at His second coming. That the Scripture mentions the blood of the grape has been evidently designed, because Christ derives blood not from the seed of man, but from the power of God. Justin Martyr (A.D. 160) Ante-Nicene Fathers vol.1 pg.222

I affirm that He announced beforehand the future salvation for the human race through the blood of Christ. For the sign of the scarlet thread, which the spies, sent to Jericho by Joshua, son of Nave (Nun), gave to Rahab the harlot, telling her to bind it to the window through which she let them down to escape from their enemies, also manifested the symbol of the blood of Christ, by which those who were at one time harlots and unrighteous persons out of all nations are saved, receiving remission of sins, and continuing no longer in sin. Justin Martyr (A.D. 160) Ante-Nicene Fathers vol.1 pg.254

The Lord thus has redeemed us through His own blood, giving His soul for our souls, and His flesh for our flesh, and has also poured out the Spirit of the Father for the union and communion of God and man, imparting indeed God to men by means of the Spirit, and, on the other hand, attaching man to God by His own incarnation, and bestowing upon us at His coming immortality durably and truly, by means of communion with God, all the doctrines of the heretics fall to ruin. Irenaeus (A.D. 180) Ante-Nicene Fathers vol.1 pg. 527

As far as concerned the apostasy, indeed, He redeems us righteously from it by His own blood; but as regards us who have been redeemed, [He does this] graciously. For we have given nothing to Him previously, nor does He desire anything from us, as if He stood in need of it; but we do stand in need of fellowship with Him. And for this reason it was that He graciously poured Himself out, that He might gather us into the bosom of the Father. But vain in every respect are they who despise the entire dispensation of God, and disallow the salvation of the flesh, and treat with contempt its regeneration, maintaining that it is not capable of incorruption. But if this indeed does not attain salvation, then neither did the Lord redeem us with His blood, nor is the cup of the Eucharist the communion of His blood, nor the bread which we break the communion of His body… By His own blood he redeemed us, as also His apostle declares, “In whom we have redemption through His blood, even the remission of sins.” And as we are His members, we are also nourished by means of the creation (and He Himself grants the creation to us, for He causes His sun to rise, and sends rain when He wills). He has acknowledged the cup (which is a part of the creation) as His own blood, from which He bedews our blood; and the bread (also a part of the creation) He has established as His own body, from which He gives increase to our bodies. Irenaeus (A.D. 180) Ante-Nicene Fathers vol.1 pg.528

In like manner, too, did the Lord say to those who should afterwards shed His blood, “All righteous blood shall be required which is shed upon the earth, from the blood of righteous Abel to the blood of Zacharias the son of Barachias, whom you slew between the temple and the altar. Verily I say unto you, All these things shall come upon this generation.” He thus points out the recapitulation that should take place in his own person of the effusion of blood from the beginning, of all the righteous men and of the prophets, and that by means of Himself there should be a requisition of their blood. Now this [blood] could not be required unless it also had the capability of being saved; nor would the Lord have summed up these things in Himself, unless He had Himself been made flesh and blood after the way of the original formation [of man], saving in his own person at the end that which had in the beginning perished in Adam. Irenaeus (A.D. 180) Ante-Nicene Fathers vol.1 pg. 541

But now, by means of communion with Himself, the Lord has reconciled man to God the Father, in reconciling us to Himself by the body of His own flesh, and redeeming us by His own blood, as the apostle says to the Ephesians, “In whom we have redemption through His blood, the remission of sins;” and again to the same he says, “You who formerly were far off have been brought near in the blood of Christ;” and again, “Abolishing in His flesh the enmities, [even] the law of commandments [contained] in ordinances.” And in every Epistle the apostle plainly testifies, that through the flesh of our Lord, and through His blood, we have been saved. Irenaeus (A.D. 180) Ante-Nicene Fathers vol.1 pg.542

Christ, who was called the Son of God before the ages, was manifested in the fullness of time, in order that He might cleanse us through His blood, who were under the power of sin, presenting us as pure sons to His Father, if we yield ourselves obediently to the chastisement of the Spirit. Irenaeus (A.D. 180) Ante-Nicene Fathers vol.1 pg.575
