Trinity Sunday 2025
Proverbs 8: 22-31; Romans 5: 1-5; John 16: 12-15
To begin, something which has nothing to do with the Holy Trinity, except insofar as the Trinity is at the root of everything good. I have to tell you about an insight which blew my head apart on Tuesday evening.
I was still very much on the sick list, still not steady enough to celebrate Mass, and so I was waiting for one of the Sisters to bring me Holy Communion. As part of my preparation to receive Our Lord, I flicked my phone onto the Rosary from Lourdes. The camera was focused on the mosaic of the Annunciation in the Rosary Basilica, while the (African) priest was reading St. Luke’s account of the event.
Just as he reached the moment of Our Lady’s consent, Sister arrived, bringing the Eucharistic Jesus, and, as I received Him, it struck me with overwhelming force that, at that moment, I was in a similar position to Our Lady, both of us having the Body of the Redeemer within us. As that awareness grew in the moments after Communion, I found it filling my mind, and I was soon sobbing my heart out.
That isn’t the point, though: the point is that this is true of everyone, every time we receive Jesus in Holy Communion. Each of us is, at that moment, what Mary is and always has been, a Theotokos—a God-bearer—each carrying the living God within ourselves. That is truly mind-blowing.
Okay—after the ecstasy, go and do the laundry. What do you and I need to know about the Blessed Trinity? Firstly, it is the best that we humans can do as an attempt to describe God. We will always fall short, because God is greater than our understanding, and will always be beyond our grasp and comprehension.
This doctrine states that God is three distinct persons, yet one God. I shy away from terms like “nature” and “substance”, because it is very easy to stray into heresy. In the early centuries of the Church, during the Arian controversy, a large proportion of the Church was in heresy and schism, literally because of one iota—the Greek equivalent of the letter “i”. “The Arians put an iota, where they really shouldn’t oughter.” (I am quite chuffed with that.)
We assign to the three Persons of the Blessed Trinity the titles “Father” “Son” and “Holy Spirit”, again the best we can do. The most important aspect of the Trinity is that it is an expression of total, self-giving love. Theologians interpret it in terms of the Father eternally begetting the Son in a perpetual expression of mutual love, that love being the Holy Spirit. Once again, this is our best effort at grasping the ungraspable.
For us, the most important factor is that God does not (cannot?) keep this love to Himself. It has spilled over into the act of Creation, in whatever way Creation has taken place and continues to take place. Furthermore, it continues to spill over in ongoing love for the world, and particularly for human beings made “in the image and likeness” of God, again whatever exactly that may mean.
Essentially, from our point of view, the Holy Trinity is the ultimate expression of total love, a love which animates us. It enables us to love, and demands of us that we be people of love. If we know nothing else about the doctrine, that should be enough.
