On 27 February 380, the emperor Theodosius – newly elevated the previous year to take control of the East amid the political and military turmoil unleashed by the debacle at Adrianople -addressed an edict from his current headquarters at Thessalonica to the people of Constantinople. The text famously proclaimed the religion to be followed by ‘all the peoples’ who fell under his rule as that handed down at Rome from the apostle Peter, now maintained by the pontifex Damasus and bishop Peter of Alexandria, ‘that is,… we should believe in the single godhead of Father, Son and Holy Spirit, in equal majesty and holy trinity’. Those who subscribed to this doctrine, Theodosius ordered, were to ‘embrace the name of Catholic Christians’, while all the rest were branded heretics, whose places of assembly were denied the name of churches, and who would be smitten ‘first by divine vengeance, and afterwards by the retribution of our own punishment, which we shall enact in accordance with the judgement of Heaven’.

16 Socrates, HE, 5.8.5-10, Sozomen, HE, 7.7.2-5, identifying them now as ‘Macedonianists’, followers of a previous bishop of Constantinople. The sticking-point was their objection to the full inclusion of the Holy Spirit in the Godhead, hence also ‘Pneumatomachians’: see further Ritter, Konzil, 68–85 (who links the episode with Greg. Naz.’s complaints about theological divisions among the bishops, Autobiography, 1703–44).
17 Socrates, HE, 5.8.1 ‘bishops of his own faith’; cf. Errington, ‘Church and State’, 54 (‘select group of guaranteed orthodox bishops’).

24 Eusebius, Life of Constantine, 4.27.2 (ed. F. Winkelmann, GCS Eusebius Werke 1.1 [Berlin, 1975], 130). T. D. Barnes (e.g. Athanasius and Constantius, 172) argues on the basis of this that Constantine gave conciliar decisions the force of law, but this may read too much into Eusebius.

25 Theodosian Code, 16.1.3 (30 July 381, addressed to proconsul of Asia), cf. Sozomen, HE, 7.9.5-7.
26 For example Ensslin, Religionspolitik, 36–7; King, Emperor Theodosius, 44–6; Ritter, Ronzii, 127–30. Errington, ‘Church and State’, 64–6, while not denying direct connection with the council, sees the law as specifically addressing the circumstances of Asia. Sozomen, HE, 7.9.5 juxtaposes his report of the law with Theodosius’ endorsement (epepsēphisato) of the council’s decisions (cf. Socrates, HE, 5.8.20, Theodosius ‘sumpsēphos’ with the bishops).
27 The fact that no bishop of Antioch is named reflects the continuing division of the Nicene congregation in the city after the death of Meletius.
