Thus it can be said that "you have been sanctified" even though it is NOT a completed fact. You are in the process of being sanctified, and since God is doing it (with your coöperation), it shall surely come about.
This does not prove anything about sanctification, that God speaks of it as having already occurred when it hasn't. And besides the statement referenced in the OP was by Paul.
No, it doesn't PROVE anything about sanctification, but it is an indicator. People who are being sanctified can be spoken of as having been sanctified.
However, according to lexicons, "sanctified" has at least two distinct meanings:
1. to dedicate, separate, set apart for God
2. to purify, make righteous
Perhaps Paul used it in the first sense in 1 Cor 1:2 and this would indicate a completed fact, as the Corinthian church was set apart from the world and for God, whereas the word is used in the second sense to indicate ongoing salvation or sanctification.
On the other hand, Paul
may[/u] have been using it in the second sense, stating as a fact that the Corinthian Christians had been sanctified, when actually they (like all other Christians) are in the process.
