Well meaning but misguided Protestants like the Born Agains and cults like Iglesia Ni Cristo/Manalo, ADD, SDAs etc usually use 2 Tim. 3:16-17 to prove that the Bible is the sole authority of God’s word. But upon examining these texts disproves their misguided views.
First let us use the method of Catholic Apologist Lucas Feliers to disprove the Protestants before we see what the Church Fathers said;
If you read 2 Tim. 3:14, Paul appeals to apostolic tradition right before the Protestants’ often quoted verse 2 Tim. 3:16-17. Thus, there is an appeal to tradition before there is an appeal to the Scriptures, and Protestants generally ignore this fact.
At 2 Tim. 3:15 – Paul then appeals to the sacred writings of Scripture referring to the Old Testament Scriptures with which Timothy was raised (not the New Testament which was not even compiled at the time of Paul’s teaching). This verse also proves that one can come to faith in Jesus Christ without the New Testament.
2 Tim. 3:16 – this verse says that Scripture is “profitable” for every good work, but not exclusive. The word “profitable” is “ophelimos” in Greek. “Ophelimos” only means useful, which underscores that Scripture is not mandatory or exclusive. Protestants unbiblically argue that profitable means exclusive.
2 Tim. 3:16 – further, the verse “all Scripture” uses the words “pasa graphe” which actually means every (not all) Scripture. This means every passage of Scripture is useful. Thus, the erroneous Protestant reading of “pasa graphe” would mean every single passage of Scripture is exclusive. This would mean Christians could not only use “sola Matthew,” or “sola Mark,” but could rely on one single verse from a Gospel as the exclusive authority of God’s word. This, of course, is not true and even Protestants would agree. Also, “pasa graphe” cannot mean “all of Scripture” because there was no New Testament canon to which Paul could have been referring, unless Protestants argue that the New Testament is not being included by Paul.
2 Tim. 3:16 – also, these inspired Old Testament Scriptures Paul is referring to included the deuterocanonical books which the Protestants removed from the Bible 1,500 years later.
2 Tim. 3:17 – Paul’s reference to the “man of God” who may be complete refers to a clergyman, not a layman. It is an instruction to a bishop of the Church. So, although Protestants use it to prove their case, the passage is not even relevant to most of the faithful.
2 Tim. 3:17 – further, Paul’s use of the word “complete” for every good work is “artios” which simply means the clergy is “suitable” or “fit.” Also, artios does not describe the Scriptures, it describes the clergyman. So, Protestants cannot use this verse to argue the Scriptures are complete.
James 1:4 – steadfastness also makes a man “perfect (teleioi) and complete (holoklepoi), lacking nothing.” This verse is important because “teleioi”and “holoklepoi” are much stronger words than “artios,” but Protestants do not argue that steadfastness is all one needs to be a Christian.
Titus 3:8 – good deeds are also “profitable” to men. For Protestants especially, profitable cannot mean “exclusive” here.
2 Tim 2:21- purity is also profitable for “any good work” (“pan ergon agathon”). This wording is the same as 2 Tim. 3:17, which shows that the Scriptures are not exclusive, and that other things (good deeds and purity) are also profitable to men.
Col. 4:12 – prayer also makes men “fully assured.” Nowhere does Scripture say the Christian faith is based solely on a book.
2 Tim. 3:16-17 – Finally, if these verses really mean that Paul was teaching sola Scriptura to the early Church, then why in 1 Thess. 2:13 does Paul teach that he is giving Revelation from God orally? Either Paul is contradicting his own teaching on sola Scriptura, or Paul was not teaching sola Scriptura in 2 Tim. 3:16-17. This is a critical point which Protestants cannot reconcile with their sola Scriptura position.
What about the Church Fathers? They overwhelmingly disagree with Protestants but uphold the Biblical and Catholic position;
“True knowledge is [that which consists in] the doctrine of the apostles, and the ancient constitution of the Church throughout all the world, and the distinctive manifestation of the body of Christ according to the successions of the bishops, by which they have handed down that Church which exists in every place, and has come even unto us, being guarded and preserved without any forging of Scriptures, by a very complete system of doctrine, and neither receiving addition nor [suffering] curtailment [in the truths which she believes]; and [it consists in] reading [the word of God] without falsification, and a lawful and diligent exposition in harmony with the Scriptures, both without danger and without blasphemy; and [above all, it consists in] the pre-eminent gift of love, which is more precious than knowledge, more glorious than prophecy, and which excels all the other gifts [of God].” Irenaeus, Against Heresies, 4,33:8 ( A.D. 180-199).
“But in learning the Faith and in professing it, acquire and keep that only, which is now delivered to thee by the Church, and which has been built up strongly out of all the Scriptures….Take heed then, brethren, and hold fast the traditions which ye now receive, and write them and the table of your heart.” Cyril of Jerusalem, Catechetical Lectures, 5:12 (A.D. 350).
“It is the church which perfect truth perfects. The church of believers is great, and its bosom most ample; it embraces the fullness of the two Testaments.” Ephraem, Against Heresies ( A.D. 373).
“But since they allege the divine oracles and force on them a misinterpretation, according to their private sense, it becomes necessary to meet them just so far as to vindicate these passages, and to show that they bear an orthodox sense, and that our opponents are in error.” Athanasius, Discourse Against the Arians, I:37 (A.D. 362).
“While (the sects) mutually refute and condemn each other, it has happened to truth as to Gideon; that is, while they fight against each other, and fall under wounds mutually inflicted, they crown her. All the heretics acknowledge that there is a true Scripture. Had they all falsely believed that none existed, someone might reply that such Scripture was unknown to them. But now that have themselves taken away the force of such plea, from the fact that they have mutilated the very Scriptures. For they have corrupted the sacred copies; and words which ought to have but one interpretation, they have wrested to strange significations. Whilst, when one of them attempts this, and cuts off a member of his own body, the rest demand and claim back the severed limb…It is the church which perfect truth perfects. The church of believers is great, and its bosom most ample; it embraces the fulness (or, the whole) of the two Testaments.” Ephraem, Adv. Haeres (A.D. 373).
