Sabellianism is Judaism imported into the preaching of the Gospel under the guise of Christianity. For if a man calls Father, Son, and Holy Spirit one, but manifold as to person [prosopon], and makes one hypostasis of the three, what else does he do than deny the everlasting pre-existence of the Only begotten?… Now Sabellius did not even deprecate the formation of the persons without the hypostasis, saying, as he did, that the same God, being one in substance,(62) was metamorphosed as the need of the moment required and spoken of now as Father, now as the Son, and now as Holy Spirit. § 41. Later Montanism and the Consequences of its Exclusion from the Church In the West Montanism rapidly discarded the extravagant chiliasm of Montanus and his immediate followers; it laid nearly all the stress upon the continued work of the Holy Spirit in the Church and the need of a stricter moral discipline among Christians. This rigoristic discipline or morality was not acceptable to the bulk of Christians, and along with the Montanists was driven out of the Church, except in the case of the clergy, to whom a stricter morality was regarded as applicable. In this way a distinctive morality and mode of life came to be assigned to the clergy, and the separation between clergy and laity, or _ordo_ and _plebs_, which was becoming established about the time of Tertullian, at least in the West, was permanently fixed. (See § 42, _d_.) Tertullian, _De Exhortatione Castitatis_, 7. (MSL, 2:971.) As a Montanist, Tertullian rejected second marriage, and in this treatise, addressed to a friend who had recently lost his wife, he treated it as the foulest adultery. This work belongs to the later years of Tertullian’s life and incidentally reveals that a sharp distinction between clergy and laity was becoming fixed in the main body of the Church.
