When our blessed Lady gave the Rosary to St. Dominic, she bestowed upon us all the gift of a perfect prayer. The mysteries of the Rosary are divided up into three categories—joyful, sorrowful and glorious—each of which we can relate to in terms of our own life both in this world and in the next. It is not by accident that, without exception, all fifteen mysteries describe events that actually happened. When we say the Rosary, we are able to fill our minds with pictures of these events, focusing on the many different aspects that might occur to us as we meditate, but always with something concrete in our mind to think about.
Today, we are faced with something entirely different. Unlike the events of the Rosary, the Blessed Trinity is not something that happened in earthly time. There is no beginning to the Trinity, no end, just a limitless eternity of being, something which by its very nature is impossible for us to comprehend. It is normal, therefore, for us to have a hard time meditating on the mystery of the Trinity. Even the eloquence of St. Paul is incapable of providing us with an adequate explanation. He merely stands in awe before the enormity of the truth of an eternal God with one Nature and three Persons, exclaiming with the simple wonder of a child, “O the depths of the riches both of the wisdom and knowledge of God! How unsearchable are his judgments and his ways past finding out! For who hath known the mind of the Lord?”
If someone with the profound insights of St. Paul is incapable of explaining the Blessed Trinity, we should not feel frustrated that we lesser mortals have the same trouble. Our attitude towards the Triune God should be one of wonder, acknowledging our own inability to understand the infinite, and trusting in the divine mercy and providence of God, without question and with the same confidence as a little child holding the hands of his mother and father.
Though we might abandon our attempts to understand the Most Blessed Trinity, we should never take the extreme opposite of neglecting it. On the contrary, we should place all our thoughts, words and deeds before this God for his approval; we should offer up all our hopes and fears, our acts of adoration, repentance for our sins, thanksgiving and supplication to this Supreme Being, our Lord and Creator. When we say our prayers, every single one is addressed to this Almighty and Everlasting Father, through Jesus Christ his Son our Lord, in unity with the Holy Ghost, ever one God, world without end. And when we say our Rosary, after each of those mysteries of our Redemption, we conclude our meditation by giving glory to the Father and to the Son and to the Holy Ghost, to this God who was in the beginning, is now, and ever shall be. This God is ever at the center of our prayers, and is our final destination. Heaven is nothing more than our final and everlasting unity with this Blessed Trinity, to whom be glory for ever. Amen.
