Protestants think of justification as a judicial decision, but for Augustine and the entire Christian tradition, justification is connected with real righteousness. Now some Protestants believe in purgatory and see it as justified. Purgatory-believing Protestant Jerry L. Walls writes: "Some Protestants go so far as to insist that purgatory is tantamount to denying justification by faith. However, I insist that everything depends on what is meant by justification and faith. As Alistair McGrath has shown, the traditional view has been that justification actually makes us righteous, and that this is what ultimately restores us to a loving relationship with God. The Protestant innovation was the separation of justification from sanctification and the interpretation of the former primarily in legal and judicial terms. But since justification, understood in this way, does not make us truly righteous, it is simply inappropriate as an objection to purgatory. Erickson's objection misses the mark for the same reasons. To insist that we must be completely transformed by freely cooperating with God before we can fully enter into His presence is not to deny the fact that grace is the foundation of our relationship with Him. For His grace is exactly what takes the initiative and makes our transformation possible. Erickson's objection to purgatory implies that grace is primarily, if not exclusively, a matter of forgiveness. It is this narrowly judicial concept of grace that must be questioned."
