Luther writes: “The Father in divine things is Grammatica, for he gives the Word and is the pure fountainhead from which, if one may so speak, floweth good, excellent, pure speech. Ths Son is Dialectica; for He giveth the arrangement whereby a thing should be set in good order of succession so that conclusion and consecution by certain. But the Holy Ghost is Rhetorica, the orator, for He excellently sustaineth, bloweth, and impelleth, maketh quick and powerful, so that an impression is made and hearts are taken.”
