Jud was born in 1482 in
Guémar,
Alsace, southwest of
Strasbourg. Like his later colleague
Heinrich Bullinger, Jud was the son of a priest. His father, Johannes Jud, was from Guémar and his mother, Elsa Hochsang, was from
Solothurn. He studied at the Latin school in
Sélestat with
Martin Bucer and in 1499 he matriculated at the
University of Basel, where he met
Huldrych Zwingli. He began his studies in medicine but switched to theology under the influence of
Thomas Wyttenbach. The 1520s were a time of great productivity for Jud. On 9 March 1522, he participated in the
Affair of the Sausages during
Lent, a protest against the established food mandates of the church. That summer he translated Zwingli's petition to the bishop of Constance (
Konstanz) for the legitimization of clerical marriage from Latin into German. In June 1522, Jud was selected to be pastor at Saint Peter's in Zürich (on Zwingli's recommendation), although he did not take up his post until 2 February 1523. Jud assumed his preaching duties only four days after the First Zürich Disputation. That summer he began preaching against clerical marriage prohibitions, which resulted in a group of the nuns at petitioning to be released from their vows. The same year, he drew up the baptismal rite for the
Swiss Reformed Church in German, which still retained some Catholic elements to it. In September of that year, Jud preached a sermon in Saint Peter's against religious images, and the result was several acts of
iconoclasm in Zürich. Jud (along with Zwingli) called for the complete removal of images, desiring the restoral of the apostolic church. This call for iconoclasm was something characteristic of some French-speaking Swiss reformers as well, such as
Pierre Viret and
Guillaume Farel. Images in the church remained a point of contention between the Swiss Reformers and magistrates for another several years. The appearance of
Anabaptism in January 1525 forced the Swiss Reformers to divert their attention to this new movement. On 17 January 1525, Jud participated in a dispute alongside Zwingli and other reformers against the Anabaptists. The advent of
Anabaptism required a more detailed statement from the Swiss church than the original 1523 statement on
baptism, and Zwingli put forth a new baptismal order in 1525. The new order mandated that the ceremony be held in a parish church, the godparents were no longer asked questions about their faith, and baptismal theology was more explicitly in line with
covenant theology and not the removal of
original sin as taught by the
Catholic church. In addition to redefining baptism, a new statement appeared in 1525 on the
Lord's Supper, which Jud was largely responsible for. ==Reformation==
