Advent / Saved by Faith Alone

"It is natural that wherever Law and good works are, there will also be zeal and quarrels among people.  When one wants to be better than the other;  but especially there will be zeal against faith, which has no regard for their works and boasts only of God's grace.  Wherever Christ is, there are always such zealots..."

(Luther, Church Postil II, p. 245)
