The Little Sisters of the Poor Home for the Aged, a very conservative group, in Denver, is the group that has challenged the law’s contraceptive-coverage mandate. This would make more sense if the nuns did not already have a way around the mandate: they just have to fill out a form saying the home has a religious mission and that they object to paying for contraceptives. The essence of their challenge is that, by saying so, they become complicit, enablers of sin—because then others will make sure that their employees have coverage.
Their religious superior, Mother Loraine, claims that she cannot sign the forms because God does not want her to.
The suggestion here is that birth control has such a dirtiness, such an innate sinfulness to it that even the formal and financial separation of religious employers from the coverage—they don’t manage it, they don’t pay for it, even though their employees get it—is insufficient.
The nuns' petition said that to just fill out the form letting their insurer know they qualified so it could proceed was to “abandon their religious convictions and participate in the government’s system to distribute and subsidize contraception, sterilization, and abortion-inducing drugs and devices.” It is worth noting that, according to the filing, fully half of the funds the nuns use to run their home, according to their filing, come “from government payments (chiefly Medicaid and Medicare) for the care they provide to the needy elderly.”
Bottom line: What religious-affiliated groups like this one are insisting is that the women who work for them bear the economic cost for the "sin" they will commit in using these devices.
