Of course -- and that "completed when we..." is the final sanctification/purgatory. hence your statement expresses a belief in purgatory/final sanctification/completing of the sanctification. -- congratulations, your post expresses a belief in purgatory/final sanctification
As I, sayuncle and MadDawg have repeated over and over again Catholic belief is that we cannot sanctify ourselves -- we cannot save ourselves, all the grace, all the saving is from God. We are saved by grace alone. -- your posts are false.
your post made the false statement about MD and now it is repeating more falsehoods. Stop it.
Sanctification is not Salvation...
