Emperors Valentinian I, Gratian, and Valens reassert a law for confiscating the worship sites of non-Catholic Christians.
According to this new law against heresy:
"Previously, on behalf of the religion of Catholic sanctity, We sought to end the illicit practice of heretical assembly by commanding the confiscation of all the altars they used under the false guise of religion...
If such forbidden worship should occur, whether by permission of judges or through dishonesty, the same punishment shall ensue." [CTh 16.5.4]
So the worship sites of orthodox Christian groups will remain unmolested, but the sites of groups which fail to live up to the demands of strict orthodoxy will be taken by the government — even if the people using it thought they had official permission to do so.
