BROTHERS and SISTERS, you are the temple of the living God, as God has said, “I will live in them and walk among them, and I will be their God, and they will be My people.” Therefore, “Come out from among them, and be separate from them, says the Lord. And do not touch anything unclean, then I will receive you. And I will be your Father, and you will be My sons and daughters, says the Lord Almighty.” Therefore, having these promises, beloved, let us cleanse ourselves from all defilement of flesh and spirit, making holiness perfect in the fear of God.
Saint John Chrysostom talks about "making holiness perfect in the fear of God,"
For not to touch unclean things does not thereby make you clean, but something else is needed for becoming holy: earnestness, heedfulness, piety. And he well said, "In the fear of God." For it is possible to perfect chasteness, not in the fear of God, but for vainglory. For even if lust makes imperious demands, still if you occupy its territory with the fear of God, you have stayed its frenzy. Now by holiness here he means not chastity alone, but the freedom from every kind of sin, for he is holy who is pure. Now one will become pure, not if he is free from fornication only, but also from covetousness and envy and pride and vainglory, yes, especially from vainglory, which in everything indeed it behoves us to avoid, but much more in almsgiving, since with this distemper, it is no longer almsgiving, but display and cruelty. For when you do not do it out of mercy, but from parade, such a deed is not only no alms, but even an insult, for you have put your brother to open shame. Not then the giving money, but the giving it out of mercy, is almsgiving.
