A work containing thirty-eight “canons”, which “Hippolytus, the chief of the bishops of Rome, wrote according to the commands of the apostles”. This paraphrase for his “Apostolic Tradition” indicates the source with an explicitness unusual in a Church Order. Its alterations are much less radical than those in the Testament, and wholly new matter is limited to a brief introduction and an appendix concerned chiefly with moral and ascetic directions. The revision was made almost certainly in the fifth century and beyond reasonable doubt in Egypt. The text (originally Greek) has been preserved only in an Arabic version. The only reliable edition is the German translation by Riedel; an English version is badly needed. For the sake of completeness there may be added: SARAPION’S PRAYERS This work is not a true Church Order: it makes no pretence to apostolic origin and consists wholly of a collection of prayers drawn up by Sarapion, bishop of Thmuis, about 350. It opens with the celebrant’s part at the eucharist and closes with various benedictions. The eucharistic prayer has been strongly influenced by the Didache, the ordination prayers by Hippolytus. The most accessible edition of the Greek text is in Funk, II, pp. 158-195. Bishop John Wordsworth edited an excellent English translation. II. HIPPOLYTUS Hippolytus is a unique figure in Christian history, for he, a schismatic bishop of Rome, is honoured by the Roman church as a saint and martyr. This curious combination of qualities made him for centuries a highly enigmatic personality, of whom almost nothing was known. Many of his voluminous works were preserved and studied, and were translated into Syriac, Coptic, Arabic, Armenian and even Old Slavic. But his creation of a schism and his acceptance of its episcopate were acts so contrary to established principles that Eusebius, writing less than a century later, can describe him only as the bishop “of a church somewhere”;[33] to which description Jerome adds: “the name of whose city I have been unable to learn”.[34] That this city was in fact Rome is, to be sure, stated by not a few late patristic and medieval writers, especially in the East, but these do not hint that there was anything irregular about his tenure. Or he is assigned sees in widely different localities, sometimes as far off as Arabia and sometimes as near Rome as Portus: this last place—due, apparently, to confusion with some other martyr—was especially popular. But among Western writers Hippolytus’s episcopal rank is commonly ignored and he appears simply as “a presbyter”: the present Roman Catholic service books[35] do not call him “bishop”. The sole general agreement was as to the date of his death, which the martyrologies and other early testimony place about 235.
