"Protestantism gave expression to the feelings of insignificance and resentment; it destroyed the confidence of man in God's unconditional love; it taught man to despise and distrust himself and others; it made him a tool instead of an end; it capitulated before secular power and relinquished the principle that secular power is not justified because of its mere existence if it contradicts moral principles; and in doing all this it relinquished elements that had been the foundations of Judaeo-Christian tradition."

Escape From Freedom by Erich Fromm, page 121

Sorry if the quote is not very ecumenical, this is a book I had to read in high school and I remember enjoying it very much. I hope to be able to read it again soon.
