Teaching and Academic Life
After theological studies at the Andrei Şaguna High School in Brașov and the Theological-Pedagogical Institute in Sibiu, Munteanu obtained a doctorate in theology from the University of Cernăuți. Following his ordination in 1927, Bishop Nicolae Ivan appointed him professor at the Theological Academy in Cluj.
He spent his career in the academy's service and rose to become its rector. His pastoral and academic life converged in 1958, when, under Bishop Teofil Herineanu, he took up the work of relaunching catechesis in the Diocese of Cluj and drew up a program for teaching the faith to both children and adults.
