Other times, they are referred to more generally as 'triadic'.

These are sometimes taken as expressions about the Trinity.

Įxpressions which link together the name of the Father, the Son, and the Holy Spirit occurred very early in the History of the Christian Church. Unitarians and some Trinitarians state that this means that those early Christians were not actually Trinitarians. Trinitarians sometimes refer to Christian belief about God before the traditional statements on the Trinity as unsophisticated, 'naive', or 'incipient Trinitarianism', and that early Christians were 'proto-Trinitarian, partially Trinitarian'. Some Trinitarians agree with this, seeing a development over time towards a true understanding of the Trinity. Nontrinitarians, on the other hand, generally state that the traditional doctrine of the Trinity did not exist until centuries after the end of the New Testament period. Some Trinitarians say the doctrine of the Trinity was revealed during the time that the New Testament was written others state that it was revealed in the Patristic period ( c. The Holy Spirit was included at the First Council of Constantinople (381 AD), where the relationship between the Father, Son and Holy Spirit as one substance ( ousia) and three co-equal persons ( hypostaseis) was formally ratified. The view that the Son was "of the substance of the Father, God of God very God of very God" was formally ratified at the First Council of Nicaea in 325 AD. Some of the evidence used to support an early belief in the Trinity are triadic statements (referring to the Father, Son and Holy Spirit) from the New Testament and the Church Fathers.

Theophilus of Antioch is the earliest Church father documented to have used the word "Trinity" to refer to God.ĭebate exists as to whether the earliest Church Fathers in Christian history believed in the doctrine of the Trinity – the Christian doctrine that God the Father, God the Son ( Jesus Christ) and God the Holy Spirit are three distinct persons sharing one homoousion (essence).
