Transcribed from The Select Letters of St. Jerome translated by F.A. Wright, Harvard University Press, MCMLXIII.
Always have a book in your hand and before your eyes ; learn the psalms word by word, pray without ceasing, keep your senses on the alert and closed against vain imaginings. Let your mind and body both strain towards the Lord, overcome wrath by patience ; love the knowledge of the Scriptures and you will not love the sins of the flesh. Do not let your mind offer a lodging to disturbing thoughts, for if they once find a home in your breast they will become your masters and lead you on into fatal sin. Engage in some occupation, so that the devil may always find you busy. If the apostles who had the power to make the Gospel their livelihood still worked with their hands that they might not be a burden on any man, and gave relief to others whose carnal possessions they had a right to enjoy in return for their spiritual benefits, why should you not provide for your own future wants? Make creels of reeds or weave baskets of pliant osiers. Hoe the ground and mark it out into equal plots, and when you have sown cabbage seed or set out plants in rows, bring water down in channels and stand by like the onlooker in the lovely lines :
‘Lo, from the channelled slope he brings the stream,
Which falls hoarse murmuring o’er the polished stones
And with its bubbling flood allays the heat
Of sun-scorched fields.’
Graft barren trees with buds or slips, so that you may, after a little time, pluck sweet fruit as a reward for your labours. Make hives for bees, for to them the Proverbs send you, and by watching the tiny creatures learn the ordinance of a monastery and the discipline of a kingdom. Twist lines too for catching fish, and copy out manuscripts, so that your hand may earn you food and your soul be satisfied with reading.
