The church in the spiritual and theological sense always contains a current that is hostile to political power, that is revolutionary and anarchical. But this is not the current that society as a whole, and especially the political authorities, recognize as the church. If these many movements have failed, it is primarily because of their intrinsic nature. Spiritual currents cannot last. When they attach political power, this power attacks them in return and proclaims that the true church is that which is in alliance with it.
