His All-Holiness Jeremias II Tranos was the Patriarch of Constantinople during the last quarter of the sixteenth century. He served as patriarch for three separate periods: from 1572 to 1579, from 1580 to 1584, and from 1587 to 1595. During his first term as patriarch, Jeremias engaged in correspondence with Lutheran theologians of the University of Tubingen concerning inclinations of the Patriarchate toward a union of the Orthodox and Lutheran Churches. He was a sound theologian, an ardent reformer, and a fierce enemy to simony.
