Milan to Nicaea

Constantine and Licinius extended religious toleration and restored Christian property in 313, following Galerius's edict of 311. Constantine convened Nicaea in 325 to address disputes over the Son's relationship to the Father; controversy continued afterward.

Toleration was not the same as a state church

The 311 and 313 documents addressed persecution, worship and property. The 313 text names Constantine and Licinius and allows religious observance beyond Christianity. Neither this settlement nor Nicaea should be treated as a single instant when every Roman became Christian or doctrinal dispute ended.
