The Son of God did not want to be seen and found in heaven. Therefore he descended from heaven into this humility and came to us in our flesh, laid himself into the womb of his mother and into the manger and went on to the cross. This was the ladder that he placed on earth so that we might ascend to God on it. This is the way you must take.
Martin LutherGod does not give grace freely in the sense that He will demand no satisfaction, but He gave Christ to be the satisfaction for us.
Martin LutherTherefore we Christians, in turn, are obliged not to tolerate their wanton and conscious blasphemy.
Martin LutherHe who receives a sacrament does not perform a good work; he receives a benefit. In the mass we give Christ nothing; we only receive from Him.
Martin Luther
