Johann Faber

He eventually became minister of Lindau, Vicar-General of Constance in 1517, Chaplain and confessor to King Ferdinand I of Austria in 1524, and Bishop of Vienna in 1530.

Faber wrote his first polemic against Martin Luther, Opus adversus nova quaedam dogmata Martini Lutheri in 1522.

This was soon followed by his Malleus Haereticorum, sex libris ad Hadrianum VI summum Pontificem published in Cologne, in 1524, and Rome in 1569.

As Bishop of Vienna, his zeal was unbounded; he protected his flock by frequent preaching and numerous writings, and he held regular conferences with his clergy.

His works in three folio volumes (Cologne, 1537–40) do not contain his polemical writings; these are found in "Opuscula quaedam Joannis Fabri, Episcopi Viennensis published in Leipzig, 1537.
