When speaking of the Holy Trinity, it is perilous to attempt to invent new expressions. These invariably turn out to be old heresies. The doctrine of the Trinity is beyond our human language and comprehension, and the Church, in her teaching and in the Catechism, uses formulae that have been hammered out by the saintly Fathers and Doctors of the Church. God is one, we do not confess three Gods; the three persons are distinct, not simply masks or modes of being; and they are related to each other as Father, Son and Holy Spirit.
In practice, our response to the mystery which God Himself has made known to us about Himself, is to adore, praise, and thank Him, and to and beg Him for forgiveness, mercy and grace. We humble ourselves in a holy fear and reverence for the majesty of God.
Although God indeed invites us to friendship with Him, this is not an excuse for irreverence, frivolity or disrespect. It is an awesome privilege to be able to address God who listens lovingly to our prayers. We should make every effort to pray with gratitude for His kindness.
