When Hitler’s family lived in Linz (actually, in the nearby town of Leonding), it attended the Catholic church of St. Michael the Archangel. Both his parents have been buried in that church. Hitler visited the grave of his parents on March 12th, 1938, the day he followed his troops as they invaded Austria.
St. Michael the Archangel is a very special saint. He is essentially the commander-in-chief of God’s Heavenly Army; the military leader who leads God’s armies against Satan’s forces and during the existential war in heaven he defeats Satan
It is well known that as a boy Hitler was mesmerized with the power and the splendor of the Holy Roman Catholic Church. Consequently, it is quite possible that (at least subconsciously) he started to associate himself with St. Michael.
In other words, it is possible that he began to feel that his great and glorious Mission in life was to become a military leader who will lead the Forces of Light to the victory in the existential war against the Forces of Darkness. Which, in a way, he subsequently did.
Interestingly enough, when Heinrich Himmler was a boy, his family also attended the Catholic church of St. Michael the Archangel. Only in Munich.
