Theophilus of Antioch 181
“Are you unwilling to be anointed with the oil of God? It is on this account that we are called Christians: because we are anointed with the oil of God” (To Autolycus 1:12 [A.D. 181]).
complains that Novatus (the first anti-pope according to some scholars. He maintained re-baptism for the lapsed Christians under persecution contra Cornelius), after having been baptized on his sickbed, “did not receive the other things which ought to be partaken of according to the rule of the Church—to be sealed, that is, by the bishop and not having received this, how did he receive the Holy Ghost?” (Euseb., H. E., vi, xliii).
“After coming from the place of washing we are thoroughly anointed with a blessed unction, from the ancient discipline by which [those] in the priesthood . . . were accustomed to be anointed with a horn of oil, ever since Aaron was anointed by Moses. . . . So also with us, the unction runs on the body and profits us spiritually, in the same way that baptism itself is a corporal act by which we are plunged in water, while its effect is spiritual, in that we are freed from sins. After this, the hand is imposed for a blessing, invoking and inviting the Holy Spirit” (Baptism 7:1–2, 8:1 [A.D. 203]).
“No soul whatever is able to obtain salvation unless it has believed while it was in the flesh. Indeed, the flesh is the hinge of salvation. . . . The flesh, then, is washed [baptism] so that the soul may be made clean. The flesh is anointed so that the soul may be dedicated to holiness. The flesh is signed so that the soul may be fortified. The flesh is shaded by the imposition of hands [confirmation] so that the soul may be illuminated by the Spirit. The flesh feeds on the body and blood of Christ [the Eucharist] so that the soul too may feed on God. They cannot, then, be separated in their reward, when they are united in their works” (The Resurrection of the Dead 8:2–3 [A.D. 210]).
Cyprian of Carthage 200-258
“It is necessary for him that has been baptized also to be anointed, so that by his having received chrism, that is, the anointing, he can be the anointed of God and have in him the grace of Christ” (Letters 7:2 [A.D. 253]).
“Some say in regard to those who were baptized in Samaria that when the apostles Peter and John came there only hands were imposed on them so that they might receive the Holy Spirit, and that they were not re-baptized. But we see, dearest brother, that this situation in no way pertains to the present case. Those in Samaria who had believed had believed in the true faith, and it was by the deacon Philip, whom those same apostles had sent there, that they had been baptized inside—in the Church. . . . Since, then, they had already received a legitimate and ecclesiastical baptism, it was not necessary to baptize them again. Rather, that only which was lacking was done by Peter and John. The prayer having been made over them and hands having been imposed upon them, the Holy Spirit was invoked and was poured out upon them. This is even now the practice among us, so that those who are baptized in the Church then are brought to the prelates of the Church; through our prayer and the imposition of hands, they receive the Holy Spirit and are perfected with the seal of the Lord” (ibid., 73:9).
Sign of completion, wholeness. No lack of grace from Baptism. Mental image, bookends, Baptism to supernatural, Confirmation brings supernatural to natural world. Completion of our journey.
“[A]re not hands, in the name of the same Christ, laid upon the baptized persons among them, for the reception of the Holy Spirit?” (ibid., 74:5).
“[O]ne is not born by the imposition of hands when he receives the Holy Ghost, but in baptism, that so, being already born, he may receive the Holy Spirit, even as it happened in the first man Adam. For first God formed him, and then breathed into his nostrils the breath of life. For the Spirit cannot be received, unless he who receives first has an existence. But . . . the birth of Christians is in baptism” (ibid., 74:7).
Elevation and higher order of being. Baptized into Jesus kingdom, made in His likeness and image, royal. Hard to understand royalty. In order creation means something.
