34 They declare also that the people have been led astray by the strains of my hymns. I certainly do not deny it. That is a lofty strain, and there is nothing more powerful than it. For what has more power than the confession of the Trinity which is daily celebrated by the mouth of the whole people? All eagerly vie one with the other in confessing the faith, and know how to praise in verse the Father, Son, and Holy Spirit. So they all have become teachers, who scarcely could be disciples.
