[1] Not only did he fight for the Protestant cause as a preacher and theologian, but he was almost the only member of Luther's party who was able to confront the Roman Catholics with the weapon of literary satire.
In 1542 he published a prose satire to which Luther wrote the preface, Der Barfusser Monche Eulenspiegel und Alkoran, a parodic adaptation of the Liber conformitatum of the Franciscan Bartolommeo Rinonico of Pisa, in which the Franciscan order is held up to ridicule.
This drew reactions from Catholic scholars such as Henricus Sedulius, who published the Apologeticus aduersus Alcoranum Franciscanorum, pro Libro Conformitatum, which criticized Alberus' arguments in this satire.
[2] Of higher literary value is the didactic and satirical Buch von der Tugend und Weisheit (1550), a collection of forty-nine fables in which Alberus embodies his views on the relations of Church and State.
[1] Several of Alberus's hymns, all of which show the influence of his master Luther, have been retained in the German Protestant hymnal.
