ordo salutis

From Credo House's Theological Word of the Day, Ordo Salutus:

(Latin, “order of salvation”)

Refers to the successive order of events in the process or event of salvation. This order includes necessities such as predestination, regeneration, faith, justification, repentance, atonement, and glorification. Depending on one”s particular stance on theological issues having to do with salvation, he or she would place these events in a different sequence. For example, the Calvinist would normally place regeneration before faith in their ordo, while the Arminian would see regeneration as a result of faith. The Roman Catholic would see justification as an event and a process that takes place throughout the Christian”s life, while Protestants would see justification as a definite event resulting from faith. Therefore, the Roman Catholic and Protestant ordo would differ from one another.
