From the Retractations, ii. 21.

To write the Book on the Work of

Monks, the need which compelled me was this. When at Carthage there

had begun to be monasteries, some maintained themselves by their

own hands, obeying the Apostle; but others wished so to live on the

oblations of the faithful, that doing no work whence they might

either have or supply the necessaries of life, they thought and

boasted that they did rather fulfill the precept of the Gospel, where the Lord saith, Behold the fowls of heaven, and the lilies of the field, (Matt. vi. 26). Whence also among laics of inferior purpose, but yet fervent in zeal, there had begun to arise tumultuous contests, whereby the Church was troubled, some defending the one, others the other part. Add to this, that some of them who were for not working, wore their hair long. Whence contentions between those who reprehended and those who justified the practice, were, according to their party affections, increased. On these accounts the venerable old Aurelius, Bishop of the Church of the same city, desired me to write somewhat of this matter; and I did so. This Book begins, “Jussioni tuæ, sancte frater Aureli.”
