Information on this point may be got not only from the writings of Origen (see especially his work against Celsus), but also and above all from his history. The controversy between Dionysius of Alexandria and the Chiliasts is also instructive on the matter.
Footnote 12:[ (return) ]
The three or (reckoning Methodius) four steps of the development of church doctrine (Apologists, Old Catholic Fathers, Alexandrians) correspond to the progressive religious and philosophical development of heathendom at that period: philosophic moralism, ideas of salvation (theology and practice of mysteries), Neoplatonic philosophy, and complete syncretism.

Footnote 14:[ (return) ]
The plan of placing the apologetic theology before everything else would have much to recommend it, but I adhere to the arrangement here chosen, because the advantage of being able to represent and survey the outer ecclesiastical development and the inner theological one, each being viewed as a unity, seems to me to be very great. We must then of course understand the two developments as proceeding on parallel lines. But the placing of the former parallel before the latter in my presentation is justified by the fact that what was gained in the former passed over much more directly and swiftly into the general life of the Church, than what was reached in the latter. Decades elapsed, for instance, before the apologetic theology came to be generally known and accepted in the Church, as is shown by the long continued conflict against Monarchianism.
Footnote 15:[ (return) ]
The origin of Catholicism can only be very imperfectly described within the framework of the history of dogma, for the political situation of the Christian communities in the Roman Empire had quite as important an influence on the development of the Catholic Church as its internal conflicts. But inasmuch as that situation and these struggles are ultimately connected in the closest way, the history of dogma cannot even furnish a complete picture of this development within definite limits.

See Tertullian, de pudic. 10: "Sed cederem tibi, si scriptura Pastoris, quæ sola moechos amat, divino instrumento meruisset incidi, si non ab omni concilio ecclesiarum etiam vestrarum inter aprocrypha et falsa iudicaretur;" de ieiun. 13: "Aguntur præsterea per Græcias illa certis in locis concilia ex universis ecclesiis, per quæ et altiora quæque in commune tractantur, et ipsa repræsentatio totius nominis Christiani magna veneratione celebratur." We must also take into account here the intercourse by letter, in which connection I may specially remind the reader of the correspondence between Dionysius, Bishop of Corinth, Euseb., H. E. IV. 23, and journeys such as those of Polycarp and Abercius to Rome. Cf. generally Zahn, Weltverkehr und Kirche währeud der drei ersten Jahrhunderte, 1877.

See the accounts of Christianity in Edessa and the far East generally. The Acta Archelai and the Homilies of Aphraates should also be specially examined. Cf. further Euseb., H. E. VI. 12, and finally the remains of the Latin-Christian literature of the third century—apart from Tertullian, Cyprian and Novatian—as found partly under the name of Cyprian, partly under other titles. Commodian, Arnobius, and Lactantius are also instructive here. This literature has been but little utilised with respect to the history of dogma and of the Church.
