Eastern Orthodoxy Examined
These are my two favourite quotes from early church saints, especially from the east, showing, in my opinion, an explicit testimony to Sola Scriptura:
St. Athanasius the Great (296-373 A.D.) wrote:
"These [canonical Scriptures] are fountains of salvation, that they who thirst may be satisfied with the living words they contain. In these ALONE is proclaimed the doctrine of godliness. Let no man add to these, neither let him take ought from these. For concerning these the Lord put to shame the Sadducees, and said, ‘You err, not knowing the Scriptures.’ And He reproved the Jews, saying, ‘Search the Scriptures, for these are they that testify of Me (Matt. 22:29; John 5:39).’ Festal Letter 39.6.
The beloved St. Athanasius the Great explicitly says here in the Scriptures “alone” is proclaimed the doctrine, or teaching, of godliness, and that we should not add or minus from these (cf. Deut. 4:2)." It is very unlikely that Athanasius is merely talking about the canon LIST of Scripture since he quoted Scriptures about the Scriptures themselves (Matt. 22:29, John 5:39) and a mere catalogue of books being “living words” and “fountains of salvation” that satisfy the thirst is impossible.
Next is St. Cyril of Jerusalem (c. 315-386-A.D.):
"For concerning the divine and sacred Mysteries of the Faith, WE OUGHT NOT TO DELIVER EVEN THE MOST CASUAL REMARK WITHOUT THE HOLY SCRIPTURES: nor be drawn aside by mere probabilities and the artifices of argument. Do not then believe me because I tell thee these things, unless thou receive from the Holy Scriptures the proof of what is set forth: for this salvation, which is of our faith, is not by ingenious reasonings, but by proof from the Holy Scriptures." The Catechetical Lectures of S. Cyril 4.17.
Cyril, as a Patriarch of Jerusalem, says he shouldn't be believed when he teaches on religion unless it is proven from the Scriptures, without exception: not even a "casual remark without the Holy Scriptures" can be received as binding. Therefore the Scripture alone are binding and have the highest and ultimate authority.
