The Mystery of the Holy Trinity

What is the doctrine of the Trinity? The Athanasian Creed, in common use around the sixth century, formulates it this way: "We worship one God in the Trinity and the Trinity in unity, without either confusing the persons or dividing the substance; for the person of the Father is one, the Son's is another, the Holy Spirit's another; but the Godhead of the Father, Son and Holy Spirit is one, their glory equal, their majesty coeternal." The post The Mystery of the Holy Trinity appeared first on St. John Henry Newman.
