38 Do your utmost, Venerable Brethren; explore every avenue that is open to you; have no hesitation in mustering all your authority and available resources in an effort to persuade the faithful under your charge to purify their souls by penance and to enkindle them with the fervor of piety. The "good seed" which the Council will scatter far and wide over the Church in those days must not be allowed to go to waste; it must find its way into hearts that are ready and prepared, loyal and true. If such is the case, then the forthcoming Council will indeed be for the faithful, a fruitful source of eternal salvation.
