The way of Godliness consists of these two things: True (pious) doctrines and good works. Without good works, true faith is not acceptable to God, likewise, good works are not acceptable to Him in the absence of True Faith (pious dogma).
Watchfulness cleanses the conscience and makes it lucid. Thus cleansed, it immediately shines like a light that has been uncovered, banishing such darkness. Once this darkness has been banished through constant and genuine watchfulness, the conscience then reveals things hidden from us.
Use your body, I beseech you, with moderation. Remember, with this body you will be raised from death when you come to be judged. Perhaps you have some doubt whether this could happen. If so, reflect in detail on what has already happened with your own self. Tell me, where were you a hundred years ago? Cannot the Creator who gave existence to a person that did not exist bring to life again to a person that did exist but is now dead? Every year He makes the corn spring to life that had withered and dies after it was sown. Do you suppose that He who raised Himself from the dead for our sake will have difficulty in raising us to new life? Or look at the trees. For a number of months they remain without fruit, even without leaves. But once the winter is past, they become green all over, new, as if risen from the dead. With better reason, and with greater ease shall we be called to new life. Do not listen to those who deny the resurrection of the body. Isaiah testifies: ‘The dead shall live again: the bodies of those who have died shall live.’ (Isa. 26:19) And according to the word of Daniel, ‘Many of those who sleep beneath the earth shall awaken, some to life eternal, the rest to eternal ruin.’ (Dan. 12:2)
As a ray of sun, passing through a crack, lights everything in the house and shows up even the finest dust, so the fear of the Lord, entering a man's heart, reveals to him all his sins.
But let thine apparel be plain, not for adornment, but for necessary conversing: not to minister to thy vanity, but to keep thee warm in winter, and to hide the unseemliness of the body: lest under the pretence of hiding the unseemliness, thou fall under another kind of unseemliness by thy extravagant dress.
If you have promised Christ to go by the strait and narrow way, restrain your stomach, because by pleasing it and enlarging it, you break your contract. Attend and you will hear Him who says: 'Spacious and broad is the way of the belly that leads to the perdition of fornication, and many there are who go in by it; because narrow is the gate and strait is the way of fasting that leads to the life of purity, and few there be that find it.'
If you possess the gift of mourning, hold on to it with all your might. For it is easily lost when it is not firmly established. And just as wax melts in the presence of fire, so it is easily dissolved by noise and bodily cares, and by luxury, and especially by talkativeness and levity.
Mourning according to God is sadness of soul and the disposition of a sorrowing heart, which ever madly seeks that for which it thirsts; and when it fails in its quest, it painfully pursues it, and follows in its wake grievously lamenting. Or thus: mourning is a golden spur in a soul which is stripped of all attachment and of all ties, fixed in a soul which is stripped of all attachment and of all ties, fixed by holy sorrow to watch over the heart.
The beginning of the mortification both of the soul’s desire and of the bodily members is much hard work. The middle is sometimes laborious and sometimes not laborious. But the end is insensibility and insusceptibility to toil and pain. Only when he sees himself doing his own will does this blessed living corpse feel sorry and sick at heart; and he fears the responsibility of using his own judgment.
