The Trinity: More than Just Doctrine
““Let us make man in our image,” God says in the book of Genesis (1:26), using a curious plural that seems out of place in the scriptures of a monotheistic faith. Indeed every other reference in the early Creation story speaks of God in the singular except this instance. Catholic exegesis has long seen in this grammatical peculiarity an early hint of the doctrine of the Trinity. Though fully revealed only with Christ’s coming, God began uncovering the mysterious nature of his own existence early in his revelation to man. The doctrine of the Trinity is unique to Christianity and serves to set our theology apart, but there’s more to this doctrine than a simple theological assertion to be accepted and then left alone. The Trinity matters.”
