We always begin our prayers invoking the Name of the Father, and of the Son and of the Holy Spirit. The reason is that we believe in the Trinitarian dimension of God. God is three persons with one nature. This separates us from other religions.
Our faith in the Trinity has founded on the Scripture and the Divine Revelation. The Old Testament gives a shadow reference of the Trinity. For example, in the book of Genesis, God says: Let us create human beings in our own image and likeness. The notion of Trinity is completely manifested in the New Testament. For instance, at the time of Jesus’ baptism, all the three persons of the Trinity were present.
How it is possible to have three persons in one God without dualism is a mystery to understand. Only the Blessed Mary understands this mystery clearly, as she is the beloved daughter of God the Father and the Beloved mother of God the son and the beloved spouse of the God the holy spirit.
For us what is important is the message of the Trinity. The Holy Trinity tells us about the image or nature of God. God is a relationship. The image or identity of God is love and communion.
God created us in his image and likeness. Therefore, if we want to remain as children of God, we must be in relation with one another. To love someone means to be with that person and to be for that person….
Closing fellowship with others means ceasing to live as a child of God.
