How did Martin Luther's feelings change towards the Catholic Church after he became a monk?

Answer 1

Martin Luther never became a monk, he joined the Augustinians, who are Friars. Of course we do not know his "feelings" other then what he has written, and others, who knew him, wrote. What we do know about him is that he had a extremely troubled youth, his father was overbearing and dictatorial, and that's Luther's view of his father affected his view of God. Most writers attribute his entering the Augustinians due to a vow that he made during a severe thunderstorm in which he feared for his life. He promised God that if he lived, he would enter the religious life. We do know that he entered the Augustinian Order and eventually taught in their Theologicate (Major Seminary) , although this is problematic as his knowledge of Theology and even St. Augustine and the Augustinian Order appears to be very poor. We can conclude that Luther's feelings didn't change all that much and that the insecurity that he felt in living up to his father's rule just got transferred to insecurity of living up to God's Fatherhood. This is the only reasonable explanation for his later defection and wild theories after fleeing the Order without seeking permission.
