The Sufficiency of Scripture

2 examples of Early Church understanding

"For concerning the divine and holy mysteries of the Faith, not even a casual statement must be delivered without the Holy Scriptures; nor must we be drawn aside by mere plausibility and artifices of speech. Even to me, who tell thee these things, give not absolute credence, unless thou receive the proof of the things which I announce from the Divine Scriptures. For this salvation which we believe depends not on ingenious reasoning, but on demonstration of the Holy Scriptures." - Cyril of Jerusalem; Bishop of Jerusalem, 4th Century (Catechetical Lectures, 4:17)

"They [heretics] gather their views from other sources than the Scriptures...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....It is within the power of all, therefore, in every Church, who may wish to see the truth, to contemplate clearly the tradition of the apostles manifested throughout the whole world; and we are in a position to reckon up those who were by the apostles instituted bishops in the Churches, and to demonstrate the succession of these men to our own times; those who neither taught nor knew of anything like what these heretics rave about. For if the apostles had known hidden mysteries, which they were in the habit of imparting to 'the perfect' apart and privily from the rest, they would have delivered them especially to those to whom they were also committing the Churches themselves. For they were desirous that these men should be very perfect and blameless in all things, whom also they were leaving behind as their successors, delivering up their own place of government to these men; which men, if they discharged their functions honestly, would be a great boon to the Church, but if they should fall away, the direst calamity....proofs of the things which are contained in the Scriptures cannot be shown except from the Scriptures themselves." - Irenaeus, 2nd Century (Against Heresies, 1:8:1, 3:1:1, 3:3:1, 3:12:9)
