Among the known lost works of Kempf are De modo confitendi peccata venialia; all of his letters; and treatises on the Lord's Prayer, the Apostles' Creed and the Ten Commandments written for Elizabeth of Luxembourg. Kempf is reported to have translated several works, including some of his own, into German, but none of these survive. Among these translations are his own De discretione, De capitulo and De affectibus formandis in horis sive officio divino; sermons of Pseudo-Augustine and Pseudo-Origen; the Tractatus de proprietate monachorum of Heinrich von Langenstein; and works of Jean Gerson. On the basis of these reports, Kempf has been associated with the Viennese school of translation. The translation of the Carthusian statutes into German at Gaming may have taken place under Kempf's supervision.
