I was not commissioned to preach by any man in this world, nor by any lord, but by Him who is the Lord of lords and by the Holy Trinity.
E fu in quel tempo che io montai quassù, e dissi che io non era mandato a predicarti da uomo del mondo, né da signore alcuno, ma da colui che è signore dei signori e dalla santa Trinità.
