Belief in God as the Holy Trinity, Father, Son, and Holy Spirit, is central to Christianity and, amazingly, all of the mainstream Christian and evangelical Christian denominations believe in God as the Trinity. Christians disagree about almost everything, including the books that make up the Bible, how to interpret the Bible, how one is saved, morality, spirituality, heaven, hell, and purgatory, the Church, the Sacraments, grace, and more, but we agree about the Holy Trinity even though the word Trinity is never used in the Bible.
The doctrine of the Trinity is that God is one God, with the three persons of God united in one Divine nature. God the Father is fully God, God the Son is fully God, and God the Holy Spirit is fully God, but they are all united as the one true God. There are many ways to try to explain the Trinity, like the three leaf clover or the image of God as a family, but they all fall short of the reality and fail to explain some aspect of the Trinity. In reality God is an infinite sharing of love between Father, Son, and Holy Spirit from all eternity, without beginning or ending. This is a great mystery, one that we will never fully comprehend on earth, and probably not even in heaven.
We can’t fully comprehend the Trinity because God is truly infinite. He’s not infinite like we say the universe is infinite. The universe is unimaginably large, but matter and energy can never be truly created or destroyed naturally, so there must be a certain amount of stuff in the universe. God is truly infinite, without limit. You could sooner explore every planet in the universe than explore the depths of the mystery of God. You can never fully comprehend God, but you can gain more understanding of Him through prayer and meditation. God is a mystery not in the sense of being incomprehensible but in the sense that there is always more to explore.
We don’t believe in some immaterial force of the universe or some distant clockmaker God who started the universe but wants nothing to do with it. We believe in a personal God, a God of infinite love, who has invited each one of us into His inner life, the love shared between God the Father, Son, and Holy Spirit. So spend some time this Trinity Sunday contemplating who God is, how He’s been at work in your life, and how He might be calling you to share in His life.
