Essence of Arianism: God the Father is absolutely unique and transcendent. Since the being or essence (ousia) of the Godhead is unique, transcendent and indivisible it cannot be shared or communicated. Therefore, whatever else exists must have come into existence by an act of God’s creation.

Deductions: 1) The Son must be a creature, 2) As a creature the Son must have a beginning, 3) The Son can have no communion with, and indeed no direct knowledge of His Father, 4) The Son must be liable to change and even sin.

Conclusion: The Son of God was not eternal, was not always with God, but was made by the Father before all time. Key phrase of Arianism: “there was [a time] when he was not.”

For Arianism, the Son of God is of similar substance/essence (homoiousios) with the Father.

Refutation by the Nicene Creed (325 AD): the Son of God is of the same substance/essence (homoousios) with the Father – “We believe…the Son of God, begotten from the Father, only-begotten, that is, from the substance of the Father, God from God, light from light, true God from true God, begotten not made, of one substance with the Father.”

One paramount issue facing the early church was how to harmonize belief in the deity of the Son of God with monotheism. The early church had to clarify the relationship between Jesus and the one God of the Old Testament.

Prominent heretical sects which offered one-sided solutions include 1) Gnosticism and Docetism which deny the humanity of Christ and 2) Ebionism and Adoptionism (Dynamic Monarchism) which denied the deity of Christ.

The early church countered these heresies with the Rule of Faith which affirmed that belief in 1) the one God who is Father, Son, and Holy Spirit and 2) the life, death, resurrection and deity of Jesus Christ to be non-negotiable. The affirmation was called the Rule of Faith. Because the Rule of Faith was so universal and consistent, the early “Church Fathers” could use it against heresies. The Rule of Faith eventually took the form of the Apostles’ Creed.

Critics of Christianity claim that the doctrine of Trinity was created by the church in the 4th century during the Council of Nicaea convened by Emperor Constantine to serve his political agenda.

While the word “Trinity” is not found in the New Testament, nevertheless, the Trinitarian pattern found throughout the New Testament, that is, the invocation of God in the name of Father, Son, and Spirit, and their divine functions and mutual relationships in the prayers and worship throughout the New Testament confirms that the Triune God was foundational in the life and practice right at the beginning of the New Testament church.

The problem of the Trinity was being raised and answered in the New Testament. It arose because of the development of Christian experience, worship, and thought. It was rooted in experience, for men were conscious of the power of the Spirit and the presence and Lordship of the risen Christ. It was rooted in worship, because men worshipped in the Spirit, offered their prayers to God the Father through Christ, and sometimes worshipped Christ himself. It was rooted in thought, because the writers tackled first the Christological problem, and then, at any rate in the Fourth Gospel, the threefold problem. The whole matter was based on the life and resurrection of Jesus himself, who received the Spirit during his earthly life and imparted the Spirit to others after his resurrection (Oscar Cullmann).

In short, the New Testament account of the work of God through Christ in the Spirit, which was based on the believers’ concrete experience of salvation rather than speculative, abstract metaphysics, provides the basis for Christian thought about the Triune God.
