The Most Holy Trinity

Today’s readings

Talking about the mystery of the Most Holy Trinity is perhaps the most daunting tasks for a preacher, but also one of the greatest privileges.  Here is one of the great mysteries of our faith, one that cries out for explanation, one that has kept the best minds of our religion occupied throughout time, and one that we, very likely, won’t completely understand until that day when we see our God face to face.

You may have heard me tell one of my favorite stories about Saint Augustine with regard to the Trinity.  The story goes that he was walking along the beach one day, trying to figure out the nature of the Holy Trinity.  As he walked along, he came across a little boy who had dug a hole in the sand right next to the shore.  With his little hands he was carrying water from the ocean and was dumping it in the little hole. St. Augustine asked, “What are you doing, my child?”  The child replied, “I want to put all of the water of the ocean into this hole.”  So St. Augustine asked him, “But is it possible for all of the water of this great ocean to be contained in this little hole?”  And the child asked him in return, “If the water of the ocean cannot be contained in this little hole, then how can the Infinite Trinitarian God be contained in your mind?”  With that the child disappeared.

We know, of course, the essential teaching: that we acknowledge and worship just one God, who embodies three divine persons – Father, Son and Holy Spirit.  What that means for us as believers, though, is something that truly takes a lifetime, and then some, to figure out.

Just like any of the mysteries of our faith, the mystery of the Most Holy Trinity is not one that can be appreciated in a vacuum, outside of relationship with the God we worship and adore.  And that’s just as well, I think, because, as Saint Thomas Aquinas taught, the Trinity can perhaps best be described as a relationship.  The Father loves the Son and the Son loves the Father, and the Holy Spirit is the love between the Father and the Son.  And this makes sense to us on some levels, because we all have been taught, and we all accept, that God is love.  And not just the kind of paltry love that our pop culture and society calls love, but love in the deepest of all senses, the kind of love that is self-giving and that intimately shares in the life of the other.  God is love, but God is better than the best love our feeble human minds can picture.  The love that is God is a love so pure that it would wholly consume us if we gave ourselves to it completely.  Just as difficult as it is for our minds to describe the Holy Trinity, so that love that is God is impossible for our minds to grasp.

But it is a love that can be experienced and lived.  We have seen, in the recent observance of Lent and celebration of the fifty days of Easter, that our God won’t stop at anything to be love for us.  Our sins were obstacles, horribly offensive to God, cutting us out of that intimate relationship and destining us for eternal destruction.  But God wasn’t having any of that.  No, instead he gave his Son, his only begotten One, to be our Savior, to pay the price for our sins, to die our death and to rise to new life so that we could have that too.  That is the love of God so deeply expressed in our religious experience.  And it’s a love we’re called to share, as we lay down our lives for our brothers and sisters, renouncing selfishness and allowing ourselves to get caught up in the lives of others.  I’ve experienced that over the last two and a half years that I’ve been here at Notre Dame, and I rejoice everyday at being part of this community.  It’s a feeling that I have for my family, of course, and I pray that you all experience it in your relationships as well.  Love is who God is and love is what we are called to become.

God as a relationship is a convenient concept for us, because our needs change during our lives, depending where we are on the journey.  Sometimes we need a parent.  And so relating to God as Father reminds us of the nurturing of our faith, being protected from evil, being encouraged to grow, and being corrected when we stray.  If you’ve had difficulty with a parent in your life, particularly a father, then relating to God as Father can also be difficult.  But still, I think there is a part of all of us, no matter what our earthly parents have been like, that longs to have a loving parental relationship.  God as Father can be that kind of parent in our lives.

And sometimes we need the Son.  Relating to God the Son – Jesus our brother – reminds us that God knows our needs, he knows our temptations, he’s experienced our sorrows and celebrated our joys.  God in Christ has walked our walk and died our death and redeemed all of our failures out of love for us.  God the Son reminds us that God, having created us in his own image and likeness, loves what he created enough to become one of us.  Our bodies are not profane place-holders for our souls, our bodies are temples of the Holy Spirit, and that very body was good enough to become the dwelling place of God when he came to earth.  Maybe you’ve never had a brother or sister or never were close to yours, but in Christ you have the brother above all others who is present to you in all your joys and sorrows.

Sometimes, too, we need a Holy Spirit.  Because we often have to be reminded that there is something beyond ourselves.  That this is not as good as it gets.  As wonderful as our world and our bodies can be, we also know they are very flawed.  The Holy Spirit reminds us that there is a part of us that always longs for God, no matter how far we have strayed.  The Spirit reminds us that our sins are not who we are and that repentance and forgiveness are possible.  It is the Holy Spirit that enables us to do the really good things we wouldn’t be capable of all by ourselves, the really good things that are who we really are before God.

It might seem like this mystery of the Trinity is a purely academic discussion. Does the Trinity affect our daily lives or make a difference in our here and now?  Is all this discussion just talk, or does it really make any difference?  Obviously, I don’t think it’s just talk.  Instead, the Most Holy Trinity must be shared with people in every time and place.  God the Father, Son and Holy Spirit wants to relate to all of us, be present to all of us, and call all of us to discipleship through common baptism, and it’s up to us to point the way to that Trinity of love that longs to be in loving relationship with all people.

However we need to relate to God right now, the good news is that he is there for us, giving us that relationship.  God is Triune because he wants to encompass our lives from beginning to end, from conception to life eternal.  Getting caught up in the relationship that is God is the project of our lives, and enables us to cry out with the Psalmist today, “O Lord, our God, how wonderful your name in all the earth!”
