Numbers 20:17

8. In the sequel we go on to speak thus: “The apostle, in concluding his discussion of marriage and of virginity, is careful to observe a mean course in discriminating between them, and, turning neither to the right hand nor to the left, he keeps to the King’s highway, and thus fulfils the injunction, ‘Be not righteous overmuch.’ Moreover, when he goes on to compare monogamy with digamy, he puts digamy after monogamy, just as before he subordinated marriage to virginity.” Do we not clearly show by this language what is typified in the Holy Scriptures by the terms right and left, and also what we take to be the meaning of the words “Be not righteous overmuch”? We turn to the left if, following the lust of Jews and Gentiles, we burn for sexual intercourse; we turn to the right if, following the error of the Manichæans, we under a pretence of chastity entangle ourselves in the meshes of unc …

20. I lay great emphasis on these points that I may deliver a young man who is dear to me from the itching both of the tongue and of the ears: that, since he has been born again in Christ, I may present him without spot or wrinkle as a chaste virgin, chaste in mind as well as in body; that the virginity of which he boasts may be more than nominal and that he may not be shut out by the bridegroom because being unprovided with the oil of good works his lamp has gone out. In Proculus you have a reverend and most learned prelate, able by the sound of his voice to do more for you than I with my written sheets and sure to direct you on your path by daily homilies. He will not suffer you to turn to the right hand or to the left or to leave the king’s highway; for to this Israel pledges itself to keep in its hasty passage to the land of promise. …

34. This, however, I take to be generally admitted, that just as it is not safe for those who walk on a lofty tight rope to lean to either side, for even though the inclination seems slight, it has no slight consequences, but their safety depends upon their perfect balance: so in the case of one of us, if he leans to either side, whether from vice or ignorance, no slight danger of a fall into sin is incurred, both for himself and those who are led by him. But we must really walk in the King’s highway, and take care not to turn aside from it either to the right hand or to the left, as the Proverbs say. For such is the case with our passions, and such in this matter is the task of the good shepherd, if he is to know properly the souls of his flock, and to guide them according to the methods of a pastoral care which is right and just, and worthy of our true Shepherd.
