Merton on the need for a critique of religion.

If in practice the function of organized religion turns out to be nothing more than to justify and to canonize the routines of mass society; if organized religion abdicates its mission to disturb man in the depths of his conscience, and seeks instead simply to ‘make converts’ that will smilingly adjust to the status quo, then it deserves the most serious and uncompromising criticism. Such criticism is not a disloyalty. On the contrary, fidelity to truth and to God demands it.
