Letter 58 to Presbyter Paulinus of Nola
5. Since you ask me as a brother in what path you should walk, I will be open with you. If you wish to take duty as a presbyter, and are attracted by the work or dignity which falls to the lot of a bishop, live in cities and walled towns, and by so doing turn the salvation of others into the profit of your own soul. But if you desire to be in deed what you are in name – a monk, that is, one who lives alone, what have you to do with cities which are the homes not of solitaries but of crowds? Every mode of life has its own exponents.
(trans. Fremantle, Lewis, and Martley 1893: 121)
