In a way, to think about Trinity Sunday is to simply acknowledge that God is love. To try to do even more than that can cause us to run the risk of getting it wrong about God. Three persons, one God. On the surface it seems easy enough, but in reality, it is a mystery beyond our ability to comprehend. God is love. But if we are to really understand even a little what it means to say God is love, we have to consider what love is. That is probably more true today when the word is used for so many things.
In the English language, love is such an imprecise word. We use it to describe the way we feel about objects, even those that are not terribly important. We can say we “love it” when someone says something funny or interesting. Even when we speak the words to another person, we can be saying something that we really do not mean. We might say “I love you” as a way to get what we want. Sadly, the way which we use the word can be far from what it meant when love is used in its truest sense, to describe God.
Consider first some examples of human love that give us a glimpse of divine love. Think of the case of a parent and child. When we see that in action, when we sense the deep love of a child for father or mother, or a parent with love for a son or daughter, there is something really beautiful about that. When two people fall in love and get married, we get a glimpse of something holy and divine. When we see the passion of someone really following a dream to make the world a better place, such as a doctor or nurse committed to serve the most vulnerable, it is not difficult at all to see goodness.
Unfortunately I need to look no farther than my own life to see that I do not really love as often as I might think I do. I want to do heroic things. And even with those persons I love, such as my mother or my brother, I do not always seem to be able to love in a consistent and truthful way. Sometimes I allow unimportant things to take over my desire to seek always the good, namely God, and the good for the creatures he has made.
But at the same time, sometimes I do love. I can consider the good and the dignity of another and meet them in helping them in their needs. Sometimes I can set aside my selfishness and give something of importance to another. Sometimes I can even make a sacrifice for the good of another.
