They gather their views from other sources than the Scriptures... (Irenaeus)
Since, therefore, the tradition from the apostles does thus exist in the Church, and is permanent among us, let us revert to the Scriptural proof furnished by those apostles who did also write the Gospel, in which they recorded the doctrine regarding God, pointing out that our Lord Jesus Christ is the truth, and that no lie is in Him. (Irenaeus)
We have learned from none others the plan of our salvation, than from those through whom the Gospel has come down to us, which they did at one time proclaim in public, and, at a later period, by the will of God, handed down to us in the Scriptures, to be the ground and pillar of our faith. (Irenaeus)
The phrase handed down is the verb form of the word tradition. What he is saying, then, is that the transmission of apostolic teaching is traditioned by means of Scripture. He writes further that the apostles committed to the Church the fullness of Gods revelation, and therefore, all things pertaining to the truth.
It is clear that Irenaeus taught that Scripture is the pillar and ground of the faith. His reference to the apostles lodging the fullness of truth in the hands of the Church is primarily a reference to Scripture. He does assert that the Church possesses the truth which anyone can ascertain by listening to her preaching, and emphasizing that to embrace the teaching of the Church is to embrace the tradition of the truth:
Suppose there arise a dispute relative to some important question among us, should we not have recourse to the most ancient Churches with which the apostles held constant intercourse, and learn from them what is certain and clear in regard to the present question? For how should it be if the apostles themselves had not left us writings? Would it not be necessary, [in that case,] to follow the course of the tradition which they handed down to those to whom they did commit the Churches? (Irenaeus)
Irenaeus proposes here a hypothetical situation. The Churches have received the tradition of the truth from the apostles. What, he asks, if they had not left us any writings? Then it would be necessary to follow the teaching, the tradition, of those Churches which have had direct contact with the apostles. The operative phrase here is, what if the apostles had not left us their writings. But in point of fact they have left us their writings. And the point he makes is that while the Church does preach and teach orally, the doctrinal content of that preaching and teaching is directly verifiable from the written Scriptures. Irenaeus is not affirming the existence of oral tradition. He is simply presenting a hypothetical situation as a way of combating the Gnostic heretics.
The Bible is the means by which the traditio (tradition), or teaching of the apostles is transmitted from generation to generation and by which true apostolic teaching can be verified and error refuted. Irenaeus actually uses a form of the word tradition to convey this idea.
I believe that is out of context. Due to the 2nd posting I put up. IMHO He really is pointing out that only certain People(apostolic tradition) can interpret it. But I see why you believe it as such. This view started with James White I believe. Thank you for discourse.
