He made his First Holy Communion at age 9 and was confirmed at 18. Upon graduation from Marcin Wadowita high school in Wadowice, he enrolled in Cracow’s Jagiellonian University in 1938 and in a school for drama.
The Nazi occupation forces closed the university in 1939 and young Karol had to work in a quarry (1940-1944) and then in the Solvay chemical factory to earn his living and to avoid being deported to Germany.
In 1942, aware of his call to the priesthood, he began courses in the clandestine seminary of Cracow, run by Cardinal Adam Stefan Sapieha, archbishop of Cracow. At the same time, Karol Wojtyla was one of the pioneers of the “Rhapsodic Theatre,” also clandestine.
After the Second World War, he continued his studies in the major seminary of Cracow, once it had re-opened, and in the faculty of theology of the Jagiellonian University, until his priestly ordination in Cracow on November 1, 1946.
Soon after, Cardinal Sapieha sent him to Rome where he worked under the guidance of the French Dominican, Garrigou-Lagrange. He finished his doctorate in theology in 1948 with a thesis on the topic of faith in the works of St. John of the Cross. At that time, during his vacations, he exercised his pastoral ministry among the Polish immigrants of France, Belgium and Holland.
