They are the Church who are a people united to the Priest, and the flock which adheres to its Pastor. From this you ought to know that the Bishop is in the Church, and the Church is in the Bishop; and if anyone is not with the Bishop, that he is not in the Church, and that those who flatter themselves and creep in, and commune secretly with some, do so in vain, not having peace with God's Priests; while the Church, which is universal and one, is not cut nor divided, but is indeed connected and bound together by the bond of Priests who unite with one another.
Why then is this day called Theophany? Because Christ made Himself known to all -- not then when He was born -- but then when He was baptised. Until this time He was not known to the people. And that the people did not know Him, Who He was...
And Jesus, when He was baptised, went up straightway out of the water; and lo, the heavens were opened unto Him, and He saw the Spirit of God descending like a dove, and lighting upon Him; and lo, a voice from heaven saying: 'This is My beloved Son, in whom I am well pleased.' The Spirit did not descend on Christ while He was down in the water, but when He came out of it. By this, the wisdom of God seeks to show us that the Spirit of God does not descend on the old man, who is alive to sin and dead to God, but only on the man spiritually re-born, who has died to sin and come alive to God.
As therefore the Lord does nothing without the Father, for says He, 'I can of mine own self do nothing,' so do you, neither presbyter, nor deacon, nor layman, do anything without the bishop.
