There followed a quick succession of professorates, with rapid promotion: Professor of Latin at Bucharest’s Nifon Seminary (1937–38); New Testament Professor at the University of Warsaw’s Faculty of Orthodox Theology (1938–39), where he replaced the celebrated professor Nicolae Arseniev. In Warsaw, he established the following Polish-language courses: “General and specific introduction to the holy books of the New Testament”; “Exegesis of Saint Paul’s Epistle to the Galatians”; and “Exegesis of the prologue to the Gospel of John”. These courses were examined by professors Milan Șesan and Vladimir Prelipceanu, who “determined their scientific and didactic value, as well as their full harmony with the teachings of the Orthodox Church”.
