Clement of Alexandria

More grievous and painful is this persecution, which arises from within, which is ever with a man, and which the persecuted cannot escape; for he carries the enemy about everywhere in himself. Thus also burning which attacks from without works trial, but that from within produces death. War also made on one is easily put an end to, but that which is in the soul continues till death.

With such persecution, if you have worldly wealth, if you have brothers allied by blood and other pledges, abandon the whole wealth of these which leads to evil; procure peace for yourself, free yourself from protracted persecutions; turn from them to the Gospel; choose before all the Saviour and Advocate and Paraclete of your soul, the Prince of life. "For the things which are seen are temporary; but the things which are not seen are eternal." And in the present time are things evanescent and insecure, but in that to come is eternal life.
