out Judea; next went forward into the wide world, publishing the same doctrine to the Gentiles, and establishing Churches in every city. From these in turn the faith has been, and still is, propagated continually for the creation of new churches, which, as well as the first founded, are called Apostolic, as being the offspring of those which were really such. Every family must be referred to its first original: therefore these Churches, many though they be and flourishing, yet are but one, that one original which the Apostles established, and from which they all spring. So they are all original, and all Apostolic, all being one. That oneness is evidenced by their loving inter-communion, and the name of brotherhood, and the interchange of hospitality; and these common rights are secured solely by their unanimous tradition of one and the same sacred covenant.
From this point, therefore, we begin our plea against all who preach a new doctrine. If the Lord Jesus Christ sent the Apostles to preach, it follows that no other preachers are to be received, but those whom Christ appointed, because "no one knoweth the Father but the Son, and he to whom the Son hath revealed Him." And it seems that the Son has revealed Him to no others than the Apostles, whom He sent to preach that doctrine, of course, which He revealed to them. But what they preached, that is, what Christ revealed to them, I shall here also plead should be proved in no other way, than by means of those same Churches, which the Apostles themselves founded, by preaching to them, as well as by word of mouth, as afterwards by Epistles. If these things are so, it follows immediately that all doctrine that agrees with those Apostolical Churches, the depositaries and sources of the faith, is to be reckoned for truth, preserving, as they doubtless do, what they received from the Apostles, the Apostles from Christ, Christ from God. But that every other doctrine is to be presumed false, that savours of contradiction to the truth of the Churches, and of the Apostles, and of Christ, and of God.
It only remains then to prove, whether this our doctrine, the rule of which we have given above, is to be considered of Apostolic tradition; and from this very fact, whether the rest come not of falsehood. Now our very inter-communion with the
