So the thread still continues. No, we do not believe in post-apostolic revelation. The Church is being built upon the foundation of the Apostles and N.T. prophets, Christ Jesus being the corner stone (see Eph. 2:20-22; 3:3-6, 9). That’s one of the basic reasons we can’t accept “faiths” like Mormonism or Islam. I saw this post on another thread, thought you people would be interested:
“The holy and inspired Scriptures are fully sufficient for the proclamation of the truth." St. Athanasius (Against the Heathen, I:3)
“Regarding the things I say, I should supply even the proofs, so I will not seem to rely on my own opinions, but rather, prove them with Scripture, so that the matter will remain certain and steadfast.” St. John Chrysostom (Homily 8 On Repentance and the Church, p. 118, vol. 96 TFOTC)
“Let the inspired Scriptures then be our umpire, and the vote of truth will be given to those whose dogmas are found to agree with the Divine words.” St. Gregory of Nyssa (On the Holy Trinity, NPNF, p. 327).
“We are not entitled to such license, I mean that of affirming what we please; we make the Holy Scriptures the rule and the measure of every tenet; we necessarily fix our eyes upon that, and approve that alone which may be made to harmonize with the intention of those writings.” St. Gregory of Nyssa (On the Soul and the Resurrection NPNF II, V:439)
“What is the mark of a faithful soul? To be in these dispositions of full acceptance on the authority of the words of Scripture, not venturing to reject anything nor making additions. For, if ‘all that is not of faith is sin’ as the Apostle says, and ‘faith cometh by hearing and hearing by the Word of God,’ everything outside Holy Scripture, not being of faith, is sin.” Basil the Great (The Morals, p. 204, vol 9 TFOTC).
“We are not content simply because this is the tradition of the Fathers. What is important is that the Fathers followed the meaning of the Scripture.” St. Basil the Great (On the Holy Spirit, Chapter 7, par. 16)
“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 you these things, give not absolute credence, unless you 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. St. Cyril of Jerusalem” (Catechetical Lectures, IV:17, in NPNF, Volume VII, p. 23.)
“Neither dare one agree with catholic bishops if by chance they err in anything, but the result that their opinion is against the canonical Scriptures of God.” St. Augustine (De unitate ecclesiae, chp. 10)
“Similarly we also, who by His will have been called in Christ Jesus, are not justified by ourselves, or our own wisdom or understanding or godliness, nor by such deeds as we have done in holiness of heart, but by that faith through which Almighty God has justified all men since the beginning of time. Glory be to Him, forever and ever, Amen.” - St. Clement of Rome (Letter to the Corinthians, par. 32)
“Indeed, this is the perfect and complete glorification of God, when one does not exult in his own righteousness, but recognizing oneself as lacking true righteousness to be justified by faith alone in Christ.” - St. Basil the Great (Homily on Humility, PG 31.532; TFoTC vol. 9, p. 479)
“They said that he who adhered to faith alone was cursed; but he, Paul, shows that he who adhered to faith alone is blessed.” - St. John Chrysostom (First Corinthians, Homily 20, PG 61.164)
“For you believe the faith; why then do you add other things, as if faith were not sufficient to justify? You make yourselves captive, and you subject yourself to the law.” - St. John Chrysostom (Epistle to Titus, Homily 3, PG 62.651).
