Threefold Mystery

The doctrine of the Trinity – that God the Father, Jesus the begotten Son of God, and the Holy Spirit are equal but distinct members of a single Godhead – is an article of faith that lies at the core of Christian belief. As the Catechism of the Catholic Church puts it, it is a mystery hidden by God, inaccessible by reason alone, and only known because God has revealed it. So should historians, as well as theologians, be concerned with it? I believe there are good reasons why we should.
