The trend regarding state mandates toward religious organizations is to offer a very narrow statutory exemption from these laws for a subset of such entities, mainly parishes, while requiring all other organizations—religious schools, charities, hospitals, universities—to bow to secular laws and requirements. The argument is that these activities are “secular” in nature, and that the churches engaged in them may not bring their religious beliefs to bear on these properly secular activities. There is a concerted effort on the part of Planned Parenthood, the ACLU, and some labor unions to eliminate Catholic ethical and religious control over Catholic hospitals, charities, nursing homes, and other facilities. If this effort is successful in bringing the courts to tell the Church which of its ministries are Catholic and which are not, then the Catholic Church (along with other religions) will be forbidden to respond to the Lord’s command to serve the poor, the sick, and the abandoned in his name. Such laws will not be held to violate the free exercise clause so long as they have no discriminatory purpose. In other words, consistent with the free exercise clause, the state could require hospitals to perform abortions so long as it imposed this requirement on all hospitals.
