What are the founding principles of the Lutheran denomination of Christianity?
Martin Luther found great resonance in a concept from the Bible he called “justification by grace through faith.” In this concept, he came to believe that human beings are not saved (justified) by any actions that they can take to improve their standing in the eyes of God because humans are inherently imperfect and inherently sinful because we are born with original sin. Instead, Luther came to believe that human beings are saved by God’s love for us (grace) through our faith in him and in Jesus Christ. There are other key principles of Lutheranism, but this concept is the philosophical and theological underpinning of Lutheranism (and most Protestantism).
