In fact it seems unlikely that the final regulations will be this broad. Here is what the March 2006 Consultation Paper said about the issue:
Churches, mosques and many other religious organisations advance their faith or belief through activities such as worship, teaching and preaching, officiating in marriage, conducting baptisms and giving sacraments to members of their religious community. We recognise that there may be circumstances where the new regulations could impact on aspects of religious activity or practice in the light of the doctrines of some faiths concerning sexual orientation and the beliefs of their followers. We need to consider therefore the application of the regulations in these areas.
We are interested to hear views on the impact that the regulations may have in these areas, particularly where the regulations may impede religious observance or practices that arise from the basic doctrines of a faith. Any exceptions from the regulations for religious organisations would need to be clearly defined and our starting point is that these should be limited to activities closely linked to religious observance or practices that arise from the basic doctrines of a faith.
