SOLA SCRIPTURA
SOLA FIDE
SOLA GRATIA
"Nevertheless, sacred doctrine makes use of these authorities as extrinsic and probable arguments; but properly uses the authority of the canonical Scriptures as an incontrovertible proof, and the authority of the doctors of the Church as one that may properly be used, yet merely as probable. For our faith rests upon the revelation made to the apostles and prophets who wrote the canonical books, and not on the revelations (if any such there are) made to other doctors. Hence Augustine says (Epis. ad Hieron. xix, 1): "Only those books of Scripture which are called canonical have I learned to hold in such honor as to believe their authors have not erred in any way in writing them. But other authors I so read as not to deem everything in their works to be true, merely on account of their having so thought and written, whatever may have been their holiness and learning."--St. Thomas Aquinas, Summa Theologia, Part 1, Question 1, Article 8
“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).
“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.)
"It is impossible either to say or fully to understand anything about God beyond what has been divinely proclaimed to us, whether told or revealed, by the sacred declarations of the Old and New Testaments." St. John of Damascus, On the Orthodox Faith, Book I, Chapter 2

Scripture Alone

The Sower sows the seed of His Word (Luke 8:4-15).  This Word is living and powerful (Hebrews 4:9-13) to conceive new life in those who hear it.  But the planting of Christ is attacked by the devil, the world, and the flesh.  Satan snatches the Word away from hard hearts.  The riches and pleasures of life choke off faith.  Shallow and emotional belief withers in time of temptation and trouble.  But see how Christ bears this attack for us!  Christ's cross was planted in the hard and rocky soil of Golgotha.  A crown of thorns was placed upon His head.  Satan and His demons hellishly hounded and devoured Him.  Yet, through His dying and rising again, He destroyed these enemies of ours.  Jesus is Himself the Seed which fell to the ground and died in order that it might sprout forth to new life and produce much grain.  In Him, the weak are strong (2 Corinthians 11:19-12:9).  He is the Word of the Father which does not return void (Isaiah 55:10-13) but yields a harvest hundredfold.
