2nd-century Charismatic activity and Theology Justin Martyr argues that God has transferred the gift of prophecy and miracles from Judaism to the Church.
Justin Martyr speaks of the subordination of the Son. No one has heard of the trinity at this point. Unitarianism (God is unity, not a trinity (3 persons) is the doctrine taught.
“Unitarianism as a theological movement began much earlier in history; indeed it antedated trinitarianism by many decades. Christianity derives from Judaism, and Judaism was strictly Unitarian.” (Encyclopedia Americana, volume 27, 1956, P. 2941, quoted in The Doctrine of the Trinity, Anthony F. Buzzard and Charles F. Hunting, Atlanta Bible College and Restoration Fellowship, 1990 P. 19)

175 Tatian’s Diatessaron, the synthesization of the 4 gospels into one is written. It becomes very popular. 4 31
180 Irenaeus writes Against the Heresies 4 75
185 Irenaeus writes that the apostles did not preach until they had the “perfect knowledge” of the gospel. 2 57
185 Irenaeus writes that the church is the depository of Christian teaching, a view that is commonly held by Catholic leaders. This is partly in response to the Gnostic claim that they held the “wisdom among the perfect”. 2 57
185-254 Origen lives in Alexandria, becomes the leader of the school there, and eventually becomes a martyr. Origen was labeled a heretic years later in Christendom for making the son inferior to the father and other doctrines.
Origen is one of the examples of early Unitarian doctrine believers who were highly respected in their time later becoming vilified by Trinitarian Catholics revising history.
4 46
200 Hippolytus claims the bishopric of Rome after disagreeing with the theology of Bishop Zephyrinus and convinces local churches to join him. 4 33
Early 3rd-century charismatic activity and theology Tertullian writes of the prophecy in the Montanists movement and provides stories with revelations and visions. However, Tertullian’s earlier writings make the first mention of such major concepts as the sacraments and the Trinity and are used by modern Orthodox theologians to “prove” that these doctrines date to earliest Christianity.  However, this first mention of the Trinity is a heretical view of the doctrine.
“In not a few areas of theology, Tertullian’s
views are, of course, completely unacceptable. Thus, for
example, his teaching on the Trinity reveals a subordination of Son to Father that in the later crass form of ARIANISM the Church rejected as heretical.” From “Tertullian”. The New Catholic Encyclopedia. 13: 837.)
While Tertullian may have been using the terms around 200 AD, he was not teaching the concepts that the later Catholic Church claims, especially of the Trinity. And, Tertullian acknowledged that “the common people have now some knowledge of Christ, and think of Him as but a man” (http://www.logoslibrary.org/tertullian/apology/21.html). This also illustrates that Unitarianism (though not yet named at that point) was still the rule of faith at that time.

3rd Century Origen of Alexandria writes that the gifts continue to be experienced in the church. He notes healings and exorcisms with accompanying signs and wonders. 3 1064
Early 3rd Century Clement of Alexandria wrote to synchronize Christianity and pagan philosophies. He taught the it was important to go beyond the literal meaning of Scripture. According to Clement, Scripture doesn’t just say what it means. There are multiple levels, and going into these multiple levels allows you to find parallels between the philosophers, especially Plato, and Scripture. For example, Clement taught that the Plato’s Ineffable One was God, revealed in the Logos. This is a clear deviation from scriptures that teach against accepting worldly philosophies (Col 2:8) and allowing private interpretation (2 Pet 1:20) 1, 7 275, 86-87
