The Canons of the 217 Blessed Fathers who assembled at Carthage 2
2 Canon II
Of Preaching the Trinity.
The whole Council said: By the favour of God, by a unanimous confession the Church’s faith which through us is handed down should be confessed in this glorious assembly before anything else; then the ecclesiastical order of each is to be built up and strengthened by the consent of all. That the minds of our brethren and fellow bishops lately elevated may be strengthened, those things should be propounded which we have certainly received from our fathers, as the unity of the Trinity, which we retain consecrated in our senses, of the Father, and of the Son, and of the Holy Ghost, which has no difference, as we say, so we shall instruct the people of God. Moreover by all the bishops lately promoted it was said: So we openly confess, so we hold, so we teach, following the Evangelic faith and your teaching.
