The Fathers sometimes speak as if Baptism was primarily the Sacrament of remission of sins, and upon that came the gift of the Spirit, which notwithstanding was but begun in Baptism and completed in Confirmation.  Vid. Tertullian. de Bapt. 7, 8, supr. i. 5 fin.  Hence, as in the text, Baptism may be said to be made up of two gifts, Water, which is Christ’s blood, and the Spirit.  There is no real difference between this and the ordinary way of speaking on the subject;—Water, which conveys both gifts, is considered as a type of one especially,—conveys both remission of sins through Christ’s blood and the grace of the Spirit, but is the type of one, viz. the blood of Christ, as the Oil in Confirmation is of the other.  And again, remission of sins is a complete gift given at once, sanctification an increasing one.  (R.W.C.)  See Index, “Baptism.”
