It is the human way of doing things. We set up categories, myths, and substitutes. We have a pigeon hole for everything. We organize it. We try to make it perfect, tension free.
Nothing can stay in repose.
It is only out of tension that redemption can come. The church in tension is the church in its natural habitat. The business of the church keeps it always on duty on the borderline of tension between the mighty opposites. Faith has to do with acceptance even when I'm not certain. Faith has to do with the most fundamental of human experiences.
