If health insurance is made madatory, will Christian Scientists be exempt from buying it?

If not, won't that be an interference with the freedom of religion guaranteed by the 1st Amendment to the Constitution?
--------------------
They can declare religious rights and be exempt from health care. I live in the People's Republic of Massachusetts and health insurance is mandatory. But a tax filer can claim religious freedom and waive the requirements. It WOULD be an interference. That's why they'll be exempt.
