The Athanasian Creed There were many Church debates about the Trinity in the 4th Century. This creed emerged probably around 360 AD and is the fullest statement of all about the issue of the Trinity.
Whosoever will be saved, before all things it is necessary that he hold the catholic faith. Which faith except everyone do keep whole and undefiled, without doubt he shall perish everlastingly. And the catholic faith is this: That we worship one God in Trinity, and Trinity in Unity, neither confounding the persons, nor dividing the substance.
The language may be old-fashioned but the meaning is clear: There is one God, and yet we worship him as a Trinity. The three persons are distinct (neither confounding the persons) and yet we do not split up the unity of God (nor dividing the substance). Moreover this is a vital part of ‘Faith that saves’; it is an element of the Catholic (which means universal) Faith. We believe there is One God, yet three persons – Father, Son and Holy Spirit.
The relationship between these three distinct persons has formed the basis of more books than can be counted – but if Jesus is not God and the Holy Spirit is not either, then much of the Bible becomes even more incomprehensible! If Jesus is no more than a super-man he is not worthy of worship; worship is reserved only for God. If the Holy Spirit is no more than a vague spiritual force then Jesus’ promise to send ‘Another Comforter’ (meaning of the same kind) has no significance.
So Christians down the ages have struggled to explain what is in fact a profound mystery. I am content to live with it; to offer worship to One God, Father, Son and Holy Spirit.
