What does the term "ordo salutis" refer to?

The term "ordo salutis" refers to the concept of the sequence of salvation events within Christian theology. This phrase, which is Latin for "order of salvation," outlines the steps or stages involved in the process of salvation, such as calling, regeneration, faith, justification, sanctification, and glorification. Understanding ordo salutis is crucial for grasping how various theological doctrines about salvation — including grace, faith, and works — interrelate and how they impact the believer's journey from initial faith to eternal life.

In contrast, the other options address different concepts. The total number of saved souls speaks to quantifying salvation rather than the process itself. The measure of faith pertains to the varying degrees of faith individuals might possess, which does not encapsulate the entire sequence of salvation. Lastly, the ultimate goal of creation relates to the overarching purpose of God's creation, which, while possibly connected to salvation, is not the same as the specific order or sequence of events that constitute salvation. Thus, the focus on the events and stages makes the first choice the correct representation of "ordo salutis."
