36 Since these things are so, suffer me awhile, holy brother, (for the Lord gives me through you great boldness,) to address these same our sons and brethren whom I know with what love you together with us travail in birth withal, until the Apostolic discipline be formed in them. O servants of God, soldiers of Christ, is it thus ye dissemble the plottings of our most crafty foe, who fearing your good fame, that so goodly odor of Christ, lest good souls should say, “We will run after the odor of your ointments,” and so should escape his snares, and in every way desiring to obscure it with his own stenches, has dispersed on every side so many hypocrites under the garb of monks, strolling about the provinces, no where sent, no where fixed, no where standing, no where sitting.
Some hawking about limbs of martyrs, if indeed of martyrs; others magnifying their fringes and phylacteries; others with a lying story, how they have heard say that their parents or kinsmen are alive in this or that country, and therefore be they on their way to them: and all asking, all exacting, either the costs of their lucrative want, or the price of their pretended sanctity. And in the meanwhile wheresoever they be found out in their evil deeds, or in whatever way they become notorious, under the general name of monks, your purpose is blasphemed, a purpose so good, so holy, that in Christ's name we desire it, as through other lands so through all Africa, to grow and flourish.
Then are you not inflamed with godly jealousy? Does not your heart wax hot within you, and in your meditation a fire kindle, that these men's evil works ye should pursue with good works, that you should cut off from them occasion of a foul trafficking, by which your estimation is hurt, and a stumbling-block put before the weak? Have mercy then and have compassion, and show to mankind that you are not seeking in ease a ready subsistence, but through the strait and narrow way of this purpose, are seeking the kingdom of God. You have the same cause which the Apostle had, to cut off occasion from them which seek occasion, that they who by their stinks are suffocated, by your good odor may be refreshed.
