Why is the Dogma of the Trinity so Important?
The day's readings can be found here.
The most central dogma of our faith is what we celebrate this Sunday: the Most Holy Trinity; the Father, and the Son, and the Holy Spirit; one God in three Persons. Surprisingly, the word “Trinity” is not found in Sacred Scripture, yet all Christians believe and profess this truth. The word comes from the Latin word trinitas, which means “a single collection of three.” The Catholic Church did not invent this doctrine, but the Church did give this most subliminal Mystery a name. Therefore, all non-Catholic Christians – even those that believe in the Bible alone – owe the development of this doctrine to the Catholic Church.
When we enter into theological discussion about the Most Holy Trinity, when we ponder this awesome Mystery, it is important to avoid using our imagination. Our imagination immediately thinks of the three Persons as three beings, but this is false. The Trinity is three Persons but one Being. Our minds cannot fathom this because we think mathematically: 1+1+1=3. This is true. However, God is not a math equation. God is utterly One, but He is one divine substance in three Persons. So, He is an infinite, incomprehensible relationship in Himself. Even though we believe this, one could ask: What does the Most Holy Trinity have to do with real life? The answer is: Everything.
And why? Because all of us are created in His image and in His likeness. We reflect the relationship that is in God – that is God – but we reflect it imperfectly. There is a perfect relationship between the Father and the Son and the Holy Spirit. The love between Father and Son is so strong, so perfect that this love produces a Person: the Holy Spirit. The Holy Spirit is the Love between Father and Son. However, when we look at ourselves, we do not see this kind of love. . . and we do not see this perfect relationship around us.
When we hate, when we gossip, when we neglect our Sunday obligation, when we lust, when we are arrogant – we deny the awesome mystery of what it means to be created in God’s image and likeness. St. Paul reminds us in the second reading that the love of God has been poured out into our hearts through the Holy Spirit that has been given to us (Romans 5:5). Do we realize how sin offends against the Love of Father and Son? Being made in the image and likeness of the Most Holy Trinity is God’s greatest gift to us. But when we sin, when we fail to love God, when we do not pray, when we do not suffer with Jesus — we do not experience His glory – and we do not experience His Love – the Love who is the Holy Spirit; the love between the Father and the Son.
