The Church is holy, although there are sinners within her. Those who sin, but who cleanse themselves with true repentance, do not keep the Church from being holy. But unrepentant sinners are cut off, whether visibly by Church authority, or invisible by the judgement of God, from the body of the Church. And so in this regard the Church remains holy.
Patriarch Philaret of MoscowLust is as it were desire and desire, will which extends beyond the natural will, passionate, not governed by the law and moderation. There are thus many forms of lust, like the many forms of sin ... Lust does not approach the soul in the form of a warlike enemy, but in the form of a friend or a pleasant servant. It suggests some sort of pleasure or illusory good. But this is only a trick by which the malicious angler strives to lead astray and catch the poor soul. Remember this when you are tempted by lust.
Patriarch Philaret of MoscowEvery Christian should find for himself the imperative and incentive to become holy. If you live without struggle and without hope of becoming holy, then you are Christians only in name and not in essence. But without holiness, no one shall see the Lord, that is to say they will not attain eternal blessedness. It is a trustworthy saying that Jesus Christ came into the world to save sinners (I Tim. 1:15). But we deceive ourselves if we think that we are saved while remaining sinners. Christ saves those sinners by giving them the means to become saints.
