The ordo salutis is the “order of salvation.” It focuses on the process of salvation and the logical order of that process. The main difference between the Arminian and Calvinist ordo concerns faith and regeneration. Strictly speaking, faith is not part of salvation in the Arminian ordo since it is the condition that is met prior to God’s act of saving. All that follows faith is salvation in the Arminian ordo while in the Calvinist ordo faith is the result of salvation in some sense. What follows is how I see the Arminian ordo compared to the Calvinist ordo along with why I find the Calvinist ordo theologically problematic.
Arminian ordo salutis:
Prevenient grace
Faith
[Union with Christ]
Justification
Regeneration
Sanctification
Glorification
