German Theology

Luther valued this booklet highly; see Spener, Pious Desires, page 141. original: "Hunc libell. magni fec. Luth. vid Spen. pia desid. p. 141." Martin Luther was the primary figure of the Protestant Reformation. Philipp Jakob Spener (1635–1705) was the "Father of Pietism," and his work Pia Desideria is a classic of Christian literature.
In fact, Luther believed it to be a small work of Tauler; see the same reference. original: "cred. quidē Luth. esse opusc. Tauleri ibid." Johannes Tauler (c. 1300–1361) was a famous German mystic. For a long time, Luther and others mistakenly attributed the anonymous Theologia Germanica to him.
Arndt published it with a preface; see the same reference. original: "Arnd. edidit cū praefat. ib." Johann Arndt (1555–1621) was an influential Lutheran theologian who helped keep the mystical tradition alive within the Protestant church.

Henry More confessed that he was awakened from a lethargy of sloth by this booklet. original: "Hoc libello excit: se è socordia veterno fassus Henr. Mor." Henry More (1614–1687) was a prominent member of the "Cambridge Platonists," a group of English philosophers who emphasized the role of reason and internal spiritual experience.
See Buddeus, Philosophy of the Hebrews, page 212. original: "vid. Budde Phil. Hebr. p 212." Johann Franz Buddeus was a historian of philosophy; the work cited here is his Introductio ad historiam philosophiae Ebraeorum.
