Thomas Merton: "The religious problem of the 20th century... chiefly one of believers."

My own peculiar task in my Church and in my world has been that of the solitary explorer who, instead of jumping on all the latest bandwagons at once, is bound to search the existential depths of faith in its silence, its ambiguities, and in those certainties which lie deeper than the bottom of anxiety. In these depths there are no easy answers, no pat solutions to anything. It is a kind of submarine life in which faith sometimes mysteriously takes on the aspect of doubt when, in fact, one has to doubt and reject conventional and superstitious surrogates that have taken the place of faith. On this level, the division between Believer and Unbeliever ceases to be so crystal clear. It is not that some are all right and others are all wrong: all are bound to seek in honest perplexity. Everybody is an Unbeliever more or less! Only when this fact is fully experienced, accepted and lived with, does one become fit to hear the simple message of the Gospel-or any other religious teaching. The religious problem of the twentieth century is not understandable if we regard it only as a problem of Unbelievers and of atheists. It is also and perhaps chiefly a problem of Believers. The faith that has grown cold is not only the faith that the Unbeliever has lost but the faith that the Believer has kept. This faith has too often become rigid, or complex, sentimental, foolish, or impertinent. It has lost itself in imaginings and unrealities, dispersed itself in pontifical and organization routines, or evaporated in activism and loose talk.
