Doesn’t a title in Latin sound fancy? I don’t know why theologians have the habit of throwing in Latin and German terms. Maybe it’s to sound intelligent. I’m not really sure.
The Ordo Salutis simply means the “order of salvation”.
When we refer to the Ordo, what we are attempting to do is seek to understand the process in which God brings about salvation. We’re trying to put it into a logical order. Hopefully, the better we understand God’s saving work in our lives, the more we will love and appreciate Him. Theology should always lead to doxology.
