Sirach14:
They don’t concur with the Church Fathers either. I mean who should we believe, the Apostles, who received their teaching from Our Lord Himself, and the Apostles in turn handed the teaching to the Fathers, and then to the Church; or do we believe someone who was born two thousand years later who has made up his mind never to believe what the RCC teaches about the Eucharist.
Catholic apologist appeal to patristic testimony is undermined the real fact they don’t heed that testimony in many areas, for example chiliasm (Rv 20):
Revelation 20:4…and they lived and reigned with Christ a thousand years. 5 But the rest of the dead lived not again until the thousand years were finished…
We must now point out how Papias… says that there will be a millennium after the resurrection from the dead, when the personal reign of Christ will be established on this earth.-Fragments of Papias, From the Exposition of the Oracles of the Lord, VI (Ante-Nicene Fathers, Vol 1, p. 154).
Or Athanasius’ rejection of any council of men as being able to promulgate doctrine not already announced in the divine scriptures:
but about the faith they wrote not,
It seemed good,' but,
Thus believes the Catholic Church;’ and thereupon they confessed how they believed, in order
to shew that their own sentiments were not novel, but Apostolical; and what they wrote down was no discovery of theirs, but is the same as was taught by the Apostles.-Councils of Ariminum and Seleucia, Part I. History of the Councils, Athanasius.
When Athanasius says:
Esti men gar hikanotera panton he theia graphe
Is indeed for sufficient above-all the of-God writing
***Context shows his characterization of Scripture as “divine” springs from his conviction it is above anything “human” ***including the councils of men:
Vainly then do they run about with the pretext that they have demanded Councils for the faith’s sake; for divine
Scripture is sufficient above all things; but if a Council be needed on the point, there are the proceedings of the Fathers, for the Nicene Bishops did not neglect this matter, but
stated the doctrine so exactly, that persons reading their words honestly, cannot but be reminded by them of the religion towards Christ announced in divine Scripture… Councils of Ariminum and Seleucia, Part I. History of the Councils, Athanasius.
Yet Catholic apologists reject this patristic testimony the church is to be ultra conservative (=sola scripturaist):
In the Lord’s apostles we possess our authority; for even they did not of themselves choose to introduce anything, but faithfully delivered to the nations (of mankind) the doctrine which they had received from Christ. If, therefore, even “an angel from heaven should preach any other gospel” (than theirs), he would be called accursed by us.- Apology, c. vi, Ante Nicene Fathers, Vol III, Wm B Eerdmans Pub, 1977 reprint, p. 246.
So when Catholics actually do heed these and other Patristic doctrines then any appeal to their teaching would at least be consistent.
Catholic inconsistency undermines their authority completely.
