Trinity & Apollinarian controversy. The divinity of the Holy Spirit. The doctrine of the Trinity according to the Cappadocian Fathers. The teaching of Apollinaris of Laodicea. The Second Ecumenical Council: Constantinople, 381. Public dimension of Arian controversy.
The whole city is full of it [controversy], the squares, the market places, the cross-roads, the alleyways; men in old-clothes, money changers, food sellers: they are all busy arguing. If you ask someone to give you change, he philosophizes about the Begotten [Son] and the Unbegotten [Father]; if you inquire about the price of a loaf, you are told by way of reply that the Father is greater and the Son inferior; if you ask ‘Is my bath ready?’ the attendant answers that the Son was made out of nothing.
Gregory of Nyssa, On the Deity of the Son (PG 46:557B).

All the people who are ruled by the administration of our Clemency shall practice that religion which the divine Peter the Apostle transmitted to the Romans… It is evident that this is the religion that is followed by the Pontiff Damasus and by Peter, Bishop of Alexandria, a man of apostolic sanctity…
We command that those persons who follow this rule [of trinitarian faith] shall embrace the name of Catholic Christians. The rest, however, whom we adjure demented and insane, shall sustain the infamy of heretical dogmas, their meeting places shall not receive the name of churches, and they shall be smitten first by divine vengeance and secondly by the retribution of our own initiative, which we shall assume in accordance with the divine judgment.”
