"better" than the societies and civic communities existing alongside of them_. The 29th and 30th chapters of the 3rd book against Celsus, in which he compares the Christians with the other population of Athens, Corinth, and Alexandria, and the heads of congregations with the councillors and mayors of these cities, are exceedingly instructive and attest the revolution of the times. In conclusion, however, we must point out that Origen expressly asserts that a person unjustly excommunicated remains a member of the Church in God's eyes; see Hom. XIV. in Levit. c. iii.: "ita fit, ut interdum ille qui foras mittitur intussit, et ille foris, qui intus videtur retineri." Doellinger (Hippolytus and Calixtus, page 254 ff.) has correctly concluded that Origen followed the disputes between Hippolytus and Calixtus in Rome, and took the side of the former. Origen's trenchant remarks about the pride and arrogance of the bishops of large towns (in Matth. XI. 9. 15; XII. 9-14; XVI. 8. 22 and elsewhere, e.g., de orat. 28, Hom. VI. in Isai c. i., in Joh. X. 16), and his denunciation of such of them as, in order to glorify God, assume a mere distinction of names between Father and Son, are also correctly regarded by Langen as specially referring to the Roman ecclesiastics (Geschichte der roemischen Kirche I. p. 242). Thus Calixtus was opposed by the three greatest theologians of the age--Tertullian, Hippolytus, and Origen.] [Footnote 245: If, in assuming the irremovability of a bishop even in case of mortal sin, the Roman bishops went beyond Cyprian, Cyprian drew from his conception of the Church a conclusion which the former rejected, viz., the invalidity of baptism administered by non-Catholics. Here, in all likelihood, the Roman bishops were only determined by their interest in smoothing the way to a return or admission to the Church in the case of non-Catholics. In this instance they were again induced to adhere to their old practice from a consideration of the catholicity of the Church. It redounds to Cyprian's credit that he drew and firmly maintained the undeniable inferences from his own theory in spite of tradition. The matter never led to a great _dogmatic_ controversy.] [Footnote 246: As to the events during the vacancy in the Roman see immediately before Novatian's schism, and the part then played by the latter, who was still a member of the Church, see my essay: "Die Briefe des roemischen Klerus aus der Zeit. der Sedisvacanz im Jahre 250" (Abhandl. f. Weizsaecker, 1892).]
