Tertullian on the Sacraments
"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]).
