It does seem futile trying to prove Sola Scriptura using ECFs when the ECFs placed so much trust in Apostolic Succession and knowing that the church they attended was founded by an Apostle of the Church. In all the reading I have done it seems that when someone quotes an ECF in support of Sola Scriptura that we must ignore their writings in their fullness or else be left with the realization that the quote is taken out of context.
Indeed, and it is also worth noting that even Jerome (who is supposed to be a hallmark defender for the protestant canon) later mentioned certain deutero's as divine and as scripture:
"Does not the SCRIPTURE say: '
Burden not thyself above thy power' [SIRACH 13:2] Jerome,
To Eustochium, Epistle 108 (A.D. 404), in NPNF2, VI:207
"Do not, my dearest brother, estimate my worth by the number of my years. Gray hairs are not wisdom; it is wisdom which is as good as gray hairs At least that is what Solomon says:
"wisdom is the gray hair unto men.’ [Wisdom 4:9]" Moses too in choosing the seventy elders is told to take those whom he knows to be elders indeed, and to select them not for their years but for their discretion (Num. 11:16)? And, as a boy, Daniel judges old men and in the flower of youth condemns the incontinence of age
(Daniel 13:55-59, or Story of Susannah 55-59, Jerome,
To Paulinus, Epistle 58, (A.D. 395), in NPNF2, VI:119
"I would cite the words
of the psalmist: 'the sacrifices of God are a broken spirit,’ [Ps 51:17]
and those of Ezekiel 'I prefer the repentance of a sinner rather than his death,’ [Ez 18:23]
AND THOSE OF BARUCH,
'Arise, arise, O Jerusalem,’ [Baruch 5:5] AND MANY OTHER PROCLAMATIONS MADE BY THE TRUMPETS OF THE
PROPHETS." Jerome,
To Oceanus, Epistle 77:4 (A.D. 399), in NPNF2, VI:159
"Wherefore, though you are already running in the way, I urge a willing horse, as the saying goes, and implore you, while you regret in your Lucinius a true brother, to rejoice as well that he now reigns with Christ. For, as
it is written in the book of Wisdom, he was "taken away lest that wickedness should alter his understanding...for his soul pleased the Lord...and he...in a short time fulfilled a long time." [Wis. 4:11-14] We may with more right weep for ourselves that we stand daily in conflict with our sins, that we are stained with vices, that we receive wounds, and that we must give account for every idle word (Mt. 12:36) St. Jerome,
Letter LXXV, 2 Schaff, Vol. 6, 399 AD, p. 155.
Certainly, when some fathers speak of a particular book as "non-canonical," they do not necessarily mean that it is not inspired or considered to be scripture. Here, Jerome uses biblical phrases, such as "it is written" and even more directly, "scripture says" when quoting the deutero's. Are we to think the Jerome is speaking out of both sides of his mouth, or more likely, he is not implying what many protestants
think he is implying (i.e. deutero's are not scripture or inspired).
