Luther's theology of the worship service was, first of all, developed on the basis of the relationship to the conflict between theolatry and idolatry. The basic presupposition of all of Luther's theology is the question: Who is your God? Luther's theology of the worship service rests first of all on the correct understanding of God and His actions and also on the faith as the integral part of humanity which is naturally connected to the true worship of God. The understanding of the mass as good deed flows, according to Luther, from the human attempts to cleanse themselves in front of God and the sacrifice of mass is one of many attempts to influence God by offering the good deeds. This leads to the understanding of the mass as idolatry tainted by legalism.
