“Now the cause, in all the points previously enumerated, of the false opinions, and of the impious statements or ignorant assertions about God, appears to be nothing else than the not understanding the Scripture according to its spiritual meaning, but the interpretation of it agreeably to the mere letter. And therefore, to those who believe that the sacred books are not the compositions of men, but that they were composed by inspiration of the Holy Spirit, agreeably to the will of the Father of all things through Jesus Christ, and that they have come down to us, we must point out the ways (of interpreting them) which appear (correct) to us, who cling to the standard of the heavenly Church of Jesus Christ according to the succession of the apostles.” Origen, First Principles, 4,1:9 (A.D. 230).
“They who are placed without the Church, cannot attain to any understanding of the divine word. For the ship exhibits a type of Church, the word of life placed and preached within which, they who are without, and lie near like barren and useless sands, cannot understand.” Hilary of Poitiers, On Matthew, Homily 13:1 (A.D. 355).
“But beyond these [Scriptural] sayings, let us look at the very tradition, teaching and faith of the Catholic Church from the beginning, which the Lord gave, the Apostles preached, and the Fathers kept.” Athanasius, Four Letters to Serapion of Thmuis, 1:28 (A.D. 360).
“This then I consider the sense of this passage, and that, a very ecclesiasitcal sense.” Athanasius, Discourse Against the Arians, 1:44 (A.D. 362).
“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 (ante A.D. 373).
“For they [heretics] do not teach as the church does; their message does no accord with the truth.” Epiphanius, Panarion, 47 (A.D. 377).
“Seeing, I say, that the Church teaches this in plain language, that the Only-begotten is essentially God, very God of the essence of the very God, how ought one who opposes her decisions to overthrow the preconceived opinion… And let no one interrupt me, by saying that what we confess should also be confirmed by constructive reasoning: for it is enough for proof of our statement, that the tradition has come down to us from our Fathers, handled on, like some inheritance, by succession from the apostles and the saints who came after them.” Gregory of Nyssa, Against Eunomius, 4:6 (c. A.D. 384).
“Wherefore all other generations are strangers to truth; all the generations of heretics hold not the truth: the church alone, with pious affection, is in possession of the truth.” Ambrose, Commentary of Psalm 118,19 (A.D. 388).
“But when proper words make Scripture ambiguous, we must see in the first place that there is nothing wrong in our punctuation or pronunciation. Accordingly, if, when attention is given to the passage, it shall appear to be uncertain in what way it ought to be punctuated or pronounced, let the reader consult the rule of faith which he has gathered from the plainer passages of Scripture, and from the authority of the Church, and of which I treated at sufficient length when I was speaking in the first book about things.” Augustine, On Christian Doctrine, 3,2:2 (A.D. 397).
" ‘So then, brethren, stand fast, and hold the traditions which ye were taught, whether by word, or by Epistle of ours.’ Hence it is manifest, that they did not deliver all things by Epistle, but many things also unwritten, and in like manner both the one and the other are worthy of credit. Therefore let us think the tradition of the Church also worthy of credit. It is a tradition, seek no farther." John Chrysostom, Homily on 2nd Thessalonians, 4:2 (A.D. 404).
“My resolution is, to read the ancients, to try everything, to hold fast what is good, and not to recede from the faith of the Catholic Church.” Jerome, To Minervius & Alexander, Epistle 119 (A.D. 406).
“But those reasons which I have here given, I have either gathered from the authority of the church, according to the tradition of our forefathers, or from the testimony of the divine Scriptures, or from the nature itself of numbers and of similitudes. No sober person will decide against reason, no Christian against the Scriptures, no peaceable person against the church.” Augustine, On the Trinity, 4,6:10 (A.D. 416).
“But it will be said, If the words, the sentiments, the promises of Scripture, are appealed to by the Devil and his disciples, of whom some are false apostles, some false prophets and false teachers, and all without exception heretics, what are Catholics and the sons of Mother Church to do? How are they to distinguish truth from falsehood in the sacred Scriptures? They must be very careful to pursue that course which, in the beginning of this Commonitory, we said that holy and learned men had commended to us, that is to say, they must interpret the sacred Canon according to the traditions of the Universal Church and in keeping with the rules of Catholic doctrine, in which Catholic and Universal Church, moreover, they must follow universality, antiquity, consent.” Vincent of Lerins, Commonitory of the Antinquity and Universality of the Catholic Faith, 70 (A.D. 434
