Among the many unsung benefits of entering the discipline of theology is the opportunity to ponder brilliant thoughts from some of the most erudite minds and sensitive spirits of history. Another unsung benefit is getting to read the bizarre nonsense that some of the same erudite minds slough off along the way.
Along the lines of Stephen Colbert’s occasional segments by the same title, I thought I’d offer two quotes (with commentary) that made me say, “That’s the craziest f#$%@# thing I’ve ever heard!”
“The concreteness of man’s ultimate concern drives him toward polytheistic structures; the reaction of the absolute element against these drives him toward monotheistic structures; and the need for a balance between the concrete and the absolute drives him toward trinitarian structures.” 
A Tillich-inspired Recipe:
- Take your ultimate concern.
- Average the concreteness of your ultimate concern with the absolute element also found therein.
- Remove the polytheistic and monotheistic by-products.
- Voila! A Trinitarian drive!
- Drop the trinitarian drive in your Volvo, and not only will your gas milage dramatically improve, but the circumincessio occuring in your engine is now totally self-lubricating!
“Thus, in fact, people become all the more indifferent to the church the more they increase in religion, and the most pious sever themselves from it proudly and coldly. Nothing can in fact be clearer than that seekers of religion are in this association [i.e. the church] only because they have no religion; they persevere in it only so long as they have none.” 
Indeed, one excellent measure for just how much true religion a person might have would be the degree of coldness and pride with which that person passes by any religious establishment. People with a wholehearted dedication to the church are clearly (nay, most clearly) the most muddleheaded irreligious shams you could ever encounter!
