Belief exists inside a person. As such, it has the power and the tendency to separate a person from his neighbors who believe differently. But authentic religion connects people rather than separates them into the elect and the misguided, the saved and those who walk in darkness. The primary function of religion, as Durkheim discovered and taught and as every congregational clergyman of any denomination has discovered for himself or herself, is to bring people together rather than to separate them, thereby increasing their joy and diluting their sorrows. For that to happen, one’s theology has to escape from the prison of the self and translate into sacred deeds shared with others, deeds sanctified by having the fingerprints of God all over them.
