Every time we make the Sign of the Cross, we are reminded how our faith rests on the great mystery we know as the Holy Trinity. This great mystery of our faith is about three persons – Father, Son, and Holy Spirit – in one God. Many images or symbols have been used to help us understand one of the deepest mysteries of our faith, the Trinity: the three leafed clover, water in its three stages. The Trinity is the central mystery of our faith. As with any deep mystery, we can probe the mystery, and have some understanding about it, but we will never have complete knowledge of the Trinity. We can even have a similar experience of the life of the Trinity: our own personal experience of human love that mirrors God’s love. But we will never approach the fullness of love that is God. Our faith keeps seeking understanding, until the day when we see God face-to-face.
