Questions of liberty (3) 33

This is from an undated article. We quote it here in order to raise a question.

Authorities in four states are prosecuting Chris­tian Science parents on manslaughter, murder, or child abuse charges for refusing medical care to their dying chil­dren. The cases — six of them in all, including three in California — represent the largest assault in history against Christian Science reliance on prayer instead of medical treatment to cure dis­ease.

Are such prosecutions against the Constitutional principle of the separation of church and state?

If so, should the state not interfere in any way in such cases?

Should the state never interfere in any religious practice whatsoever, even if – for instance – it included human sacrifice?

Debate is invited.
