priestly class among Christians, as well as the application of certain injunctions to this order (de exhort. 7: "nonne et laici sacerdotes sumus? ... adeo ubi ecclesiastici ordinis non est consessus, et offeis et tinguis et sacerdos es tibi solus, sed ubi tres, ecclesia est, licet laici."; de monog. 7). We may perhaps infer from his works that before about the year 200, the name "priest" was not yet universally applied to bishop and presbyters in Carthage (but see after this de praescr. 29, 41: sacerdotalia munera; de pud. 1, 21; de monog. 12: disciplina sacerd.; de exhort. 7: sacerdotalis ordo, ibid. 11 "et offeres pro duabus uxoribus, et commendabis illas duas per sacerdotem de monogamia ordinatum;" de virg. vel. 9: sacerdotale officium; Scorp. 7: sacerdos). The latest writings of Tertullian show us indeed that the name and the conception which it represents were already prevalent. Hippolytus (Philos. praef.: [Greek: hon hemeis diadochoi tugchanontes tes te autes charitos metechontes archierateias kai didaskalias], see also the Arabian canons) expressly claimed high priesthood for the bishops, and Origen thought he was justified in giving the name of "Priests and Levites" to those who conducted public worship among Christians. This he indeed did with reserve (see many passages, e.g., Hom. II. in Num., Vol. II. p. 278; Hom. VI. in Lev., Vol. II. p. 211; Comment, in Joh., Vol. I. 3), but yet to a far greater extent than Clement (see Bigg, l.c., p. 214 f.). In Cyprian and the literature of the Greek Church in the immediately following period we find the designation "priest" as the regular and most customary name for the bishop and presbyters. Novatian (Jerome, de vir. inl. 70) wrote a treatise _de sacerdote_ and another _de ordinatione_. The notable and momentous change of conception expressed in the idea can be traced by us through its preparatory stages almost as little as the theory of the apostolic succession of the bishops. Irenaeus (IV. 8. 3, 17. 5, 18. 1) and Tertullian, when compared with Cyprian, appear here as representatives of primitive Christianity. They firmly assert the priesthood of the whole congregation. That the laity had as great a share as the leaders of the Churches in the transformation of the latter into Priests is moreover shown by the bitter saying of Tertullian (de monog. 12): "Sed cum extollimur et inflamur adversus clerum, tunc unum omnes sumus, tunc omnes sacerdotes, quia 'sacerdotes nos deo et patri fecit'. Cum ad peraequationem disciplinae sacerdotalis provocamur, deponimus infulas."] [Footnote 261: See Sohm, I. p. 207.]
