Clement of Alexandria, on Heb 9:14

However, one ought to consider continence not merely in relation to one form of it, that is, sexual relations, but in relation to all the other indulgences for which the soul craves when it is ill content with what is necessary and seeks for luxury. It is continence to despise money, softness, property, to hold in small esteem outward appearance, to control one's tongue, to master evil thoughts. In the past certain angels became incontinent and were seized by desire so that they fell from heaven to earth. And Valentine says in the letter to Agathopus: "Jesus endured all things and was continent; It was his endeavour to earn a divine nature; he ate and drank in a manner peculiar to himself, and the food did not pass out of his body. Such was the power of his continence that food was not corrupted within him; for he himself was not subject to the process of corruption." As for ourselves, we set high value on continence which arises from love to the Lord and seeks that which is good for its own sake, sanctifying the temple of the Spirit. It is good if for the sake of the kingdom of heaven a man emasculates himself from all desire, and "purifies his conscience from dead works to serve the living God."
