The Conferences Of John Cassian by John Cassian
Chapter III. Abbot John's answer why he had left the desert.
The system of the anchorites, which you are surprised at my leaving, I not only neither reject nor refuse, but rather embrace and regard with the utmost veneration: in which system, and after I had passed thirty years living in a Coenobium, I rejoice that I have also spent twenty more, so that I can never be accused of sloth among those who tried it in a half-hearted way. But because its purity, of which I had had some slight experience, was sometimes soiled by the presence of anxiety about carnal matters, it seemed better to return to the Coenobium to secure a readier attainment of an easier aim undertaken, and less danger from venturing on the higher life of the humble solitary. For it is better to seem earnest with smaller promises than careless in larger ones. And therefore if possibly I bring forward anything somewhat arrogantly and indeed somewhat too freely, I beg that you will not think it due to the sin of boasting but rather to my desire for your edification; and that, as I think that, when you ask so earnestly, nothing of the truth should be kept back from you, you will set it down to love rather than to boasting. For I think that some instruction may be given to you if I lay aside my humility, and simply lay bare the whole truth about my aim. For I trust that I shall not incur any reproach of vainglory from you because of the freedom of my words, nor any charge of falsehood from my conscience because of any suppression of the truth.
