So declared Pope Francis recently. It's a clever statement, if the objective is to appeal to the "I'm spiritual, not religious" sentiments hostile to the notion of "institutional church." There's a sense in which it is also profoundly true.
Taylor Marshall asks: "Does that make you feel uncomfortable?" And he says: "I feel a little uncomfortable when I read that, because I'm sold on the idea of the Church as a visible "institution." However, as I chewed on this quote from the Holy Father I began to seem the wisdom in it.
Bottom line, as far as I'm concerned is this: Here's a case where it's clearly both/and, not either/or. As long as one doesn't take the expression as suggesting some sort of ethereal flight into the nebulous world of mysticism, which begins in mist and ends in schism, or, as a rejection of "institutional religion" the "institutional Church" and her religious Sacred Tradition, there should be no problem; and perhaps even a net gain. But it all depends on what you do with such appealing slogans.
