One of the best descriptions of the Triune God of Christianity was offered in the Athanasian Creed of the 4th Century:

“…we worship one God in Trinity, and Trinity in Unity; Neither confounding the persons nor dividing the substance. For there is one person of the Father, another of the Son, and another of the Holy Spirit. But the Godhead of the Father, of the Son, and of the Holy Spirit is all one, the glory equal, the majesty coeternal… And in this Trinity none is afore or after another; none is greater or less than another. But the whole three persons are coeternal, and coequal. So that in all things, as aforesaid, the Unity in Trinity and the Trinity in Unity is to be worshipped. He therefore that will be saved must thus think of the Trinity.”
