Whence is it that we are Christians? Through our faith, would be the universal answer. And in what way are we saved? Plainly because we were regenerate through the grace given in our baptism.
Baptism does not take away our free will or freedom of choice, but gives us the freedom no longer to be tyrannized by the devil unless we choose to be. After baptism it is in our power either to persist willingly in the practice of the commandments of Christ, into whom we were baptized, and to advance in the path of His ordinances, or to deviate from this straight way and fall again into the hands of our enemy...
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.
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.
