Philoxenus of Mabbug

“Brothers, I want you to know about those who sleep: you must not grieve like the rest of humanity, who have lost all hope.” Our resurrection too will take place by the power of the Holy Spirit who is within us. Because the Holy Spirit is in faithful persons when they die, their death cannot be called death, but only sleep.

That is to say, do not grieve him by sin, otherwise his light will be quenched from your soul—a light which, when kindled within you, gives you the possession of a power that is beyond expression; and you will be able to contend “with principalities and powers,” and fight against the evil spirits under heaven, and reject all the world with its pleasures and pains. All are effected by the fervor of the Spirit within us. .
