Hans Tausen (Tavsen) (1494 – 11 November 1561) was the leading Lutheran theologian of the Danish Reformation in Denmark. He served as Bishop of Ribe and published the first translation of the Pentateuch into Danish in 1535.
Hans Tausen was born at Birkende on Funen in Denmark. Very little is known about his childhood and youth, but apparently he was a pupil at the grammar schools at Odense and Slagelse, finally settling down as a friar in the monastery of the Order of Saint John of Antvorskov near Slagelse. After studying at , where he got the degree of a master of arts and also after being ordained as a priest, he studied for a short time at the University of Copenhagen, and was then again sent abroad by his prior, visiting, among other places, the newly founded University of Leuven in Belgium and making the acquaintance of the Dutch humanists. He was already a good linguist, understanding both Latin and Hebrew. Subsequently, he translated the books of Moses from the original.
In May 1523 Tausen went to Wittenberg, where he met Martin Luther and studied for a year and a half, when he was recalled to Antvorskov. In consequence of his professed attachment to the doctrines of Martin Luther he was transferred, in the spring of 1525, to the monastery of the Order of Saint John at Viborg in Jutland, where he continued to preach the Lutheran belief, and eventually was allowed to use the pulpit of the Saint Johns Church. Tausen's preaching was so revolutionary that he no longer felt safe within the Order of Saint John, so he discarded his religious habit and placed himself under the protection of the burgesses of Viborg. At first he preached in the parish church of St John, but this soon growing too small for him he addressed the people in the market-place from the church tower. When the Franciscans refused to allow him to preach in their large church, the mob broke in by force. A compromise was at last arranged, whereby the friars were to preach in the forenoon and Tausen in the afternoon. The bishop sent armed men to the church to arrest Tausen, but the burghers, who had brought their weapons with them, drove back the bishop's men. In October 1526 King Frederick I, during his visit to Aalborg, took Hans Tausen under his protection, appointed him one of his chaplains, and charged him to continue for a time to preach the Holy Gospel to the citizens of Viborg, who were to be responsible for his safety, thus identifying himself with the new doctrines in direct contravention of the plain letter of his coronation oath.
