Again we'll have to disagree.
You follow a doctrine that mixes works of the law with grace.
But instead we find in scripture that a believer's perfect obedience is to the gospel. Believe in Jesus.
Our works are to believe in Jesus, John 6:29.
God's will for us is to believe in Jesus, John 6:40.
In believing in Jesus we cleanse ourselves, we're sanctified (Heb 10:10), holy (Rom 11:16), perfected (Heb 10:14), cannot sin (1John 3:9), and righteous.
The assumption that this is all a gradual process is contradictory to scripture. Whether speaking of individual Christians or the body of Christ (as you seem to want to separate these 2), there is no gradual sanctification (as scripture clearly indicates).
And how does one defile the temple of God?
1Cor 6:18,19
Flee fornication. Every sin that a man doeth is without the body; but he that committeth fornication sinneth against his own body. What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own?
Heb 12:15-17
Looking diligently lest any man fail of the grace of God; lest any root of bitterness springing up trouble you, and thereby many be defiled;
Lest there be any fornicator, or profane person, as Esau, who for one morsel of meat sold his birthright.
How does one fail the grace of God/fornicate?
Gal 5:4
Christ is become of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace.
To be under the law (which includes the lukewarm mixing of grace with works of the law) is fornication with Hagar/the law (Gal 4:24).
Take note of God's will for us is:
1Thess 4:3
For this is the will of God, even your sanctification, that ye should abstain from fornication:
When we believe in Jesus we're sanctified through the offering of the body of Christ, Heb 10:10.
But, to fornicate with Hagar/the law results in condemnation.
You cannot mix grace with works of the law. This is fornication.
Rom 11:6
if by grace, then is it no more of works: otherwise grace is no more grace. But if it be of works, then it is no more grace: otherwise work is no more work.
