theologian university professor
Borrhaus was born in Stuttgart and raised as an adopted child of a Simon Keller.
He enrolled at the University of Tübingen, where in 1515 he graduated and came to know Philipp Melanchthon.
In 1520, he moved to the University of Ingolstadt, where he took up the study of Greek and Hebrew, and theology under Johann Eck. Following a dispute with Eck, he left for Wittenberg, where he taught mathematics at the private school of Melanchthon. However his ideas became more radical, and he was expelled for heterodoxy in April 1522.
Borrhaus travelled in the company of Felix Manz through Switzerland, Austria, Poland and Prussia.
Under the influence of Wolfgang Capito, Borrhaus published his first work, "De operibus Dei" 1527. He died in Basel. Borrhaus associated with the advocates of tolerance Sebastian Castellio, Celio Secondo Curione and Michael Servetus.
His views on the Trinity were less open in his later years, not surprisingly, given the death by burning of Servetus in 1553.
