1 Thessalonians 5:6
From the Encyclical Divinum Illud Munus, Pope Leo XIII, 1897:
Again, since He is the Spirit of Truth, whosoever faileth by weakness or ignorance may perhaps have some excuse before Almighty God; but he who resists the truth through malice and turns away from it, sins most grievously against the Holy Ghost.
In our days this sin has become so frequent that those dark times seem to have come which were foretold by St. Paul, in which men, blinded by the just judgment of God, should take falsehood for truth, and should believe in "the prince of this world," who is a liar and the father thereof, as a teacher of truth: "God shall send them the operation of error, to believe lying (2 Thess. ii., 10). In the last times some shall depart from the faith, giving heed to spirits of error and the doctrines of devils" (1 Tim. iv., 1). But since the Holy Ghost, as We have said, dwells in us as in His temple, We must repeat the warning of the Apostle: "Grieve not the Holy Spirit of God, whereby you are sealed" (Eph. iv., 30).
Nor is it enough to fly from sin; every Christian ought to shine with the splendour of virtue so as to be pleasing to so great and so beneficent a guest; and first of all with chastity and holiness, for chaste and holy things befit the temple. Hence the words of the Apostle: "Know you not that you are the temple of God, and that the Spirit of God dwelleth in you? But if any man violate the temple of God, him shall God destroy. For the temple of God is holy, which you are" (1 Cor. iii., 16-17): a terrible, in deed, but a just warning.
