32 Here is another difference between true and false reformers which you, Venerable Brethren, have often encountered. The latter "seek their own interests, not those of Jesus Christ." They listen to the deceitful invitation once addressed to the Divine Master, "Manifest thyself to the world." They repeat the ambitious words, "Let us also get us a name" and in their rashness (which We unfortunately have to deplore in these days) "some priests fell in battle, while desiring to do manfully, they went out unadvisedly to fight."
