For some people, religion isn’t something that can become unhealthy. It’s something that is unhealthy, all the time. Freud’s classic statement on the subject was that religion is a “universal obsessional neurosis.” Many mental health professionals still agree with him.
To me, this perspective is something of a caricature, but one which nevertheless contains important truths. There is in fact a lot that is unhealthy about religious beliefs and practices, as well as with the inner life that they seek to shape.
Religious beliefs are unhealthy — in the sense that they are no longer good for us — when we ask no questions about and brook no criticism of them. The beliefs may be true in themselves, but being close-minded about them is injurious to genuine growth in faith.
More than remaining just unhealthy influences, religious beliefs become downright malignant when they are gathered into a belief-system whose principal tenet is that no other belief-system, religious or otherwise, has any truth in it at all. Those who do this kind of gathering are not only obsessional; they are delusional.
The process is subtle but diabolically effective. It begins with a noble affirmation, such as “The Buddha experienced enlightenment about all things spiritual.” Then, the affirmation becomes “Only the Buddha is the truly Enlightened One.” The Buddha himself would have agreed with the first statement, but not the second.
Religious practices become unhealthy — in the sense that they lead both our feelings and our actions astray — when we engage in them for no reason other than we have been told to do so by religious leaders whose authority we do not question.
They become malignant when they take a form deliberately designed to inflict suffering in the service of the religion itself. Some examples: securing conformity to devotional and moral rules by threats of excommunication and damnation; propagating the religion by forced conversion of conquered people; slaughtering those deemed to be infidels.
The inner life that is produced by unhealthy religious beliefs and practices pales by comparison with a truly authentic spirituality. The signs of its unhealthiness are hard to miss: slavish conformity; defensiveness; anxiety masked by false confidence; guilt; shame; joylessness. It’s hard to be around spiritually unhealthy people for very long and have much regard for the religion that has made them so.
Faith-seekers deserve so much more from religion.
