One of the three affirmations of the Christian faith which the Anglican Church shares with a great many other Churches is the Athanasian Creed, which begins rather insistently:

Whosoever will be saved, before all things it is necessary that he hold the catholic faith. Which faith except every one 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 Essence.

Why would our ancestors in the faith have commended to us in such certain terms, such a specific and nuanced way of describing and understanding God? Isn't it enough to simply believe in an almighty creator? Or that Jesus died for our sins? Or to receive the Holy Spirit?

On this Trinity Sunday we will explore this mystery together, and perhaps grow to understand why so many who have lived their life with God, pray in the name of the Father, and of the Son, and of the Holy Spirit. Maybe this prayer tells us more about the Gospel than we might think a simple ritual ever could.
