8 His perception of his mission and his love for Christ continually urged this holy apostle to action. It consoled him in his afflictions, raised him in his discouragements, and inspired him with confidence when he despaired of his strength. It was evident right from his arrival in Phrygia and in Thuringia when, according to a writer of that period: "following the command of the pope, he spoke of religion to the senators and to the heads of the people and showed them the true way of knowledge and the clear light of understanding." His zeal kept him from laziness and prevented him from even thinking about rest or staying in one place as in a peaceful harbor. It spurred him to undertake difficulties and the most humble work solely to obtain or to increase the glory of God and the salvation of souls.
