“The grace of the Lord Jesus Christ and the love of God and the fellowship of the Holy Spirit be with you all” 2Cor 13:14
With the above Trinitarian benediction, the Apostle Paul closes his Second Letter to the Christians in Corinth.
Many have been said and written about the doctrine of the Holy Trinity but we have to realize that it still remains a mystery.
If there is a better and easier explanation then it is that contained in this Pauline blessing.
Three words are particularly important here: “grace”, “love” and “fellowship” (also communion, participation). Together these three qualities describe The Trinitarian Godhead. Man is invited by God’s own self-revelation and self-communication to share in these divine life and qualities not only vertically (that is in relation to God himself but also horizontally (that is in relation to his own fellows).
It is the same Trinitarian formula we embrace at the beginnings and endings of all Christian worship what we call “the sign of the cross” because we begin and end “In the name of the God, the Father and of the Son and of the Holy Spirit.”
The Trinity distinguishes Christian Faith from other religions. It is a summary of the Christian Faith (the Credo). The Apostle Paul didn’t invent the Trinitarian formula he was merely passing on a tradition, a teaching he himself have received.
Trinity is how God has revealed Himself to humanity in time and space.
The Trinity calls and challenges us to love, grace and communion.
