A church is a community constituted by certain foundational beliefs, but among those beliefs a key one is that the word of the Lord must be obeyed. That is, there are practices that are intrinsic to Christian belief properly understood, and among those are the obligations to feed the hungry, heal the sick, tend to the widows and orphans in their distress, train up children in the way they should go, and be transformed by the renewing of our minds. Thus religion, in the Biblical sense, involves not just holding certain beliefs but acting on them, and the institutions the church creates to help us carry out those commandments are just as “religious” as worshipping congregations. From that it follows that “freedom of religion,” if it is to mean anything, must be extended just as fully to those institutions as to parish churches. Otherwise the church is crippled in its obedience. Which is bad for the church, but also, and more important, bad for the world — unless you happen to think that the State, and the State only, is the proper vehicle for charity and social service.
I’m not sure about “the institutions the church creates” but worth the time to read.
