Behold, man, you have before you ‘Water and fire, life and death, good and evil,’ heaven and hell, the legitimate king and a cruel tyrant, the false sweetness of the world and the true blessedness of paradise. Power is given to you through the grace of Christ: ‘Stretch forth your hand to whichever you choose.’ ‘Choose life, that you may live’; leave the broad way on the left which drags you to death, and cling to the narrow path on the right which happily leads you to life. Do not allow the wideness of that road on the left to keep you or give you pleasure. To be sure, it is spacious and level, adorned with different kinds of flowers; but its flowers quickly fade and even between the flowers poisonous serpents frequently lie hidden, so that when you hurry on to these false joys you are struck by their deadly venom. This way is spacious, but it is not long. You pay attention to the kind of road you are walking, and do not notice what kind of a land you are reaching. If you listen to me, you withdraw yourself from death, for if you do not believe in Christ you will perish in hell, as the Lord Himself said in the Gospel: ‘Wide and broad is the way that leads to death, and many there are who enter that way.’ Truly, it gives pleasure for a time, but it deceives for all eternity. On the other hand, the road on the right should not sadden or frighten you: it is indeed narrow, but it is not long. The rejoicing on the wide path does not last long, and neither does the labor on the narrow way; after a short, broad path the former drags one into eternal straightened circumstances, while after brief difficulties the latter leads to endless bliss.
Caesarius of Arles, Sermon 151.5
