[IV.] Nor shall I find fault if your humble thanks to your instructor were further earned by your having acquired from discussions with him some other true and useful knowledge. But may I ask you what it is? Is it that the soul is not spirit, but body? Well, I really do not think ignorance on such a point is any great injury to Christian learning; and if you indulge in more subtle disputes about the different kinds of bodily substance, I think the information you obtain is more difficult than serviceable. If, however, the Lord will that I should write to this young man himself, as I desire to do, then perhaps your loving self62 Dilectio tua. will know to what extent you are not indebted to him for your instruction; although you rejoice in what you have learnt from him. And now I request you not to feel annoyance in writing me an answer; so that what is clearly useful and pertinent to our indispensable faith may not by any chance turn out to be something different.
CAPUT IV.
Et non reprehendo quod gratus fueris tanta humilitate doctori, si aliquid aliud disputante illo, verum atque utile didicisti: sed hoc quid sit inquiro; an forte animam non spiritum esse, sed corpus? Non quidem magnum doctrinae christianae arbitror esse detrimentum ista nescire: et si de corporum generibus subtiliter disputetur, hoc majore difficultate quam utilitate perdiscitur. Si autem Dominus voluerit ut ad illum ipsum juvenem scribam, sicut desidero, ibi sciet fortasse Dilectio tua, etiam hoc quam non te docuerit: si tamen id te ab illo didicisse laetaris. Sed ne quid forte aliud sit, quod constat esse utile, et ad fidem necessariam pertinere, peto rescribere non graveris.
