Massashusetts allows you to not pay for health insurance "because of sincerely-held religious beliefs"

Something I noticed while filling out my Massachusetts tax forms today:

"If you do not get health insurance because of sincerely-held religious beliefs, you can claim a religious exemption on the state tax forms."

I wonder what religious beliefs those would be?

[Background: In Massachusetts, everyone must have health insurance. Consequently, more than 95% of people have health insurance here. But, if you are self-employed or work for an employer who does not provide health insurance, you have to buy health insurance and that can be expensive ($1000 a month or higher for family cover, if you have a reasonable income and don't get subsidized plan). Perhaps this plan will be extended to the entire US. ]

Also, I guess the text above should say "commonwealth tax forms".
