“As Luther once went the lonely way between Rome and Spiritualism, so the Lutheran Church today stands alone between the world powers of Roman Catholicism on the one hand and modern Protestantism on the other. Her doctrine which teaches that the Spirit is bound to the means of grace is as inconceivable to modern people in the twentieth century as it was to their predecessors in the sixteenth. But we are convinced that behind this doctrine stands one of the most profound truths which has ever been expressed in Christian theology.”

– Herman Sasse, “The Lonely Way” (2.138)
