In 1613 the office of a judicial vicar was established in Saint Gall in a concordat with Konstanz. At the same time, parishes within the abbey's region were removed from the ecclesiastical jurisdiction of the bishop of Konstanz. P. Jodok Metzler became the first judicial vicar of the Princely Abbey of Saint Gall on 22 August 1614. During his abbacy, Müller made regular visitations to the parishes, the first in 1603 and then in 1612/13, 1615, 1618, 1621/22, and 1627.
