This past Sunday, we celebrated the Solemnity of the Most Holy Trinity, and I did a lot of reflecting on the mystery of the Trinity. Not only has God chosen a people to be His own (as He did with the Israelites), but He has revealed to us the mystery of His own interior life: that He is One God, and yet a communion of Three Divine Persons. Each Divine Person is fully God, absolutely equal in power and dignity, and yet living in a perfect communion in the One Godhead. This is a “mystery,” meaning that it is beyond the power of our limited intelligence to understand, and yet we can know with absolute certitude that it is the truth, because God has revealed it, and He can neither deceive nor be deceived.
But we also know that, when we receive the Holy Sacrament of Baptism, that we are brought into a personal relationship with the Triune God. Yes, we are washed clean from original sin, and from any personal sins that we might have committed up to that time, but that is not the central gift of baptism. We are made part of God’s Holy Catholic and Apostolic Church — but that isn’t the first truth about baptism. The central gift and truth about baptism is that we are brought into a relationship with the Holy Trinity: God, who is Father, Son, and Holy Spirit, comes to dwell within our souls. We become temples of God, and there is a permanent, unbreakable connection with the Trinity which we call the “seal” of baptism. Even if we wander far away from God — even if we renounce our relationship to Him — He is always working on us by grace, seeking to bring us back to Himself — to the One who loves us more than our parents, our spouse, our children, our brothers and sisters. Yes, God’s Love for us is infinite and unbounded, not even being limited by our sins!
So what should we do? Treasure the gift of the indwelling of the Holy Trinity, which we call Sanctifying Grace. Do nothing to separate ourselves from His indwelling (mortal sin). Seek to become aware, more and more, each day, of the presence of the Holy Trinity within us, and consciously seek to grow in our relationship with the Triune God dwelling within our souls.
