The word Baptism is derived from the Greek word, bapto, or baptizo, to wash or to immerse. It signifies, therefore, that washing is of the essential idea of the sacrament. Scripture uses the term baptize both literally and figuratively. It is employed in a metaphorical sense in Acts 1:5, where the abundance of the grace of the Holy Ghost is signified, and also in Luke 12:50, where the term is referred to the sufferings of Christ in His Passion. Otherwise in the New Testament, the root word from which baptism is derived is used to designate the laving with water, and it is employed, when speaking of Jewish lustrations, and of the baptism of John, as well as of the Christian Sacrament of Baptism (cf. Hebrews 6:2; Mark 7:4). In ecclesiastical usage, however, when the terms Baptize, Baptism are employed without a qualifying word, they are intended to signify the sacramental washing by which the soul is cleansed from sin at the same time that water is poured upon the body. Many other terms have been used as descriptive synonyms for baptism both in the Bible and Christian antiquity, as the washing of regeneration, illumination, the seal of God, the water of eternal life, the sacrament of the Trinity, and so on. In English, the term christen is familiarly used for baptize. As, however, the former word signifies only the effect of baptism, that is, to make one a Christian, but not the manner and the act, moralists hold that “I christen” could probably not be substituted validly for “I baptize” in conferring the sacrament.
