Augustine (De bono viduitatis)

As to those other things which we hold on the authority, not of Scripture, but of tradition, and which are observed throughout the whole world, it may be understood that they are held as approved and instituted either by the apostles themselves, or by plenary Councils, whose authority in the Church is most useful, . . .For often have I perceived, with extreme sorrow, many disquietudes caused to weak brethren by the contentious pertinacity or superstitious vacillation of some who, in matters of this kind, which do not admit of final decision by the authority of Holy Scripture, or by the tradition of the universal Church. (Letter to Januarius, 54, 1, 1; 54, 2, 3; cf. NPNF I, I:301)I believe that this practice [of not rebaptizing heretics and schismatics] comes from apostolic tradition, just as so many other practices not found in their writings nor in the councils of their successors, but which, because they are kept by the whole Church everywhere, are believed to have been commanded and handed down by the Apostles themselves. (On Baptism, 2, 7, 12; from William A. Jurgens, editor and translator, The Faith of the Early Fathers, 3 volumes, Collegeville, Minnesota: Liturgical Press, 1970, vol. 3: 66; cf. NPNF I, IV:430)
. . . the custom, which is opposed to Cyprian, may be supposed to have had its origin in apostolic tradition, just as there are many things which are observed by the whole Church, and therefore are fairly held to have been enjoined by the apostles, which yet are not mentioned in their writings. (On Baptism, 5,23:31, in NPNF I, IV:475)
The Christians of Carthage have an excellent name for the sacraments, when they say that baptism is nothing else than “salvation” and the sacrament of the body of Christ nothing else than “life.” Whence, however, was this derived, but from that primitive, as I suppose, and apostolic tradition, by which the Churches of Christ maintain it to be an inherent principle, that without baptism and partaking of the supper of the Lord it is impossible for any man to attain either to the kingdom of God or to salvation and everlasting life? (On Forgiveness of Sins and Baptism, 1:34, in NPNF I, V:28)
[F]rom whatever source it was handed down to the Church – although the authority of the canonical Scriptures cannot be brought forward as speaking expressly in its support. (Letter to Evodius of Uzalis, Epistle 164:6, in NPNF I, I:516)
The custom of Mother Church in baptizing infants [is] certainly not to be scorned, nor is it to be regarded in any way as superfluous, nor is it to be believed that its tradition is anything except Apostolic. (The Literal Interpretation of Genesis, 10,23:39, in William A. Jurgens, editor and translator, The Faith of the Early Fathers, 3 volumes, Collegeville, Minnesota: Liturgical Press, 1970, vol. 3: 86)
God has placed this authority first of all in his Church. (Explanations of the Psalms, Tract 103:8, PL 37:520-521, in Yves Congar, Tradition and Traditions: An Historical and Theological Essay, New York: Macmillan, 1967, 392)
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. (On the Trinity, 4,6:10; NPNF I, III:75)
It is obvious; the faith allows it; the Catholic Church approves; it is true. (Sermon 117, 6)
Will you, then, so love your error, into which you have fallen through adolescent overconfidence and human weakness, that you will separate yourself from these leaders of Catholic unity and truth, from so many different parts of the world who are in agreement among themselves on so important a question, one in which the essence of the Christian religion involved . . . ? (Against Julian I:7,34; in Robert B. Eno, Teaching Authority in the Early Church, Wilmington: Michael Glazier, 1984, 136)
And thus a man who is resting upon faith, hope, and love, and who keeps a firm hold upon these, does not need the Scriptures except for the purpose of instructing others. Accordingly, many live without copies of the Scriptures, even in solitude, on the strength of these three graces. (On Christian Doctrine, I, 39:43, in NPNF I, II:534)
And if any one seek for divine authority in this matter, though what is held by the whole Church, and that not as instituted by Councils, but as a matter of invariable custom, is rightly held to have been handed down by apostolical authority, still we can form a true conjecture of the value of the sacrament of baptism in the case of infants. (On Baptism, 4, 24, 32; NPNF I, IV:461)
It is not to be doubted that the dead are aided by prayers of the holy church, and by the salutary sacrifice, and by the alms, which are offered for their spirits . . . For this, which has been handed down by the Fathers, the universal church observes. (Sermon 172, in Joseph Berington and John Kirk, The Faith of Catholics, three volumes, London: Dolman, 1846; I: 439)
To be sure, although on this matter, we cannot quote a clear example taken from the canonical Scriptures, at any rate, on this question, we are following the true thought of Scriptures when we observe what has appeared good to the universal Church which the authority of these same Scriptures recommends to you; thus, since Holy Scripture cannot be mistaken, anyone fearing to be misled by the obscurity of this question has only to consult on this same subject this very Church which the Holy Scriptures point out without ambiguity. (Against Cresconius I:33; in Robert B. Eno, Teaching Authority in the Early Church, Wilmington: Michael Glazier, 1984, 134)
[L]et the reader consult the rule of faith which he has gathered from the plainer passages of Scripture, and from the authority of the Church . . . (On Christian Doctrine, 3,2:2, NPNF I, II:557)
