“Everything, therefore, in the Christian Church is ordered to the end that we shall daily obtain there nothing but the forgiveness of sin through the Word and signs, to comfort and encourage our consciences as long as we live here. Thus, although we have sins, the grace of the Holy Ghost does not allow them to injure us, because we are in the Christian Church, where there is nothing but continuous, uninterrupted forgiveness of sin, both in that God forgives us, and in that we forgive, bear with, and help each other.”

 

-Martin Luther

(Large Catechism, Part II, Paragraph 55)
