Baptism Gives Life by the Spirit – Gregory of Nyssa
In Holy Baptism, what is it that we secure thereby? Is it not a participation in a life no longer subject to death? I think that no one who can in any way be reckoned among Christians will deny that statement. What then? Is that life-giving power in the water itself which is employed to convey the grace of Baptism? Or is it not rather clear to every one that this element is only employed as a means in the external ministry, and of itself contributes nothing towards the sanctification, unless it be first transformed itself by the sanctification; and that what gives life to the baptized is the Spirit; as our Lord Himself says in respect to Him with His own lips, “It is the Spirit that gives life;” but for the completion of this grace He alone, received by faith, does not give life, but belief in our Lord must precede, in order that the lively gift may come upon the believer, as our Lord has spoken, “He gives life to whom He wills“.
