Oral teaching and unwritten polity admitted — yet outside the written deposit
We freely admit that the Prophets and Apostles and other men inspired by God said and taught many things by living voice that are not found set down word for word in sacred Scripture.
Nor do we deny that the Apostles and inspired men may once have ordered many things in the Church about the form of divine worship and various circumstances of church polity that are not written out in Scripture. Some historical items received from them may also have been kept among the faithful and handed on to later ages.
Latin
XXXII. Ultro quidem fatemur Prophetas & Apostolos hominesque alios a Deo inspiratos, plurima viva voce dixisse & docuisse, quae in sacris literis verbatim expressa non reperiuntur. Nec etiam negamus fieri potuisse ut Apostoli & viri θεόπνευστοι in Ecclesia olim multa ordinaverint, circa formam divini cultus, & varias Ecclesiasticae politiae circumstantias, quae non sunt in sacris literis perscripta. Atque etiam historica nonnulla ab iis accepta potuisse apud fideles conservari & transmitti ad posteros.
