The mission of the friars whom he had attracted to his form of life was to invite all people, believers and unbelievers alike, to become "authentic worshipers who will worship the Father in Spirit and truth" (Jn. 4.23). He had become convinced that his brothers were divinely commissioned to give joyous witness everywhere to the goodness and greatness of God, and to invite all men to render to their Creator and Redeemer the worship that is His due.

He had a new conviction that, as plenipotentiary preachers and practitioners of the Gospel, the friars had, as the area of their evangelizing efforts, the entire world which Christ had come to redeem and to which He had sent His Apostles. All the friars were to urge every person they met "to fear and honor, praise and bless, give thanks to and adore the Lord God Almighty, in Trinity and in Unity, Father, Son and Holy Spirit: Creator of all.”⁸
