National Association of Christian Ministers Summary Series: Theology
Christian Trinitarianism is the belief in the existence of one God who exists as three distinct persons – the Father, the Son (Jesus Christ), and the Holy Spirit. This is a fundamental doctrine of Christianity and is often referred to as the Trinity.
Trinitarianism teaches that the Father, Son, and Holy Spirit are coequal and coeternal, each possessing the fullness of the divine nature. While they are distinct persons, they are not separate beings, but rather three persons in one Godhead.
The doctrine of the Trinity emphasizes the unity and diversity of God, and is central to Christian worship and theology. Trinitarianism affirms that God is love, and that this love is expressed in the relationship between the Father, Son, and Holy Spirit.
The doctrine has been the subject of much theological reflection and debate throughout Christian history, particularly in the early Church. It is often associated with the concept of salvation, and with the Christian understanding of God’s relationship with humanity.
Trinitarianism is widely accepted by many Christian denominations, including the Roman Catholic, Eastern Orthodox, and Protestant Churches. It is considered a core belief of Christianity and is often cited in the creeds of the Church, such as the Nicene Creed.
