"The mystery of the Most Holy Trinity is the central mystery of Christian faith and life. It is the mystery of God in himself. It is therefore the source of all the other mysteries of faith, the light that enlightens them. It is the most fundamental and essential teaching in the hierarchy of the truths of faith" - Catechism of the Catholic Church, 234
(Gospel Text: JN 16:12-15)
Jesus said to his disciples:
"I have much more to tell you, but you cannot bear it now.
But when he comes, the Spirit of truth,
he will guide you to all truth.
He will not speak on his own,
but he will speak what he hears,
and will declare to you the things that are coming.
He will glorify me,
because he will take from what is mine and declare it to you.
Everything that the Father has is mine;
for this reason I told you that he will take from what is mine
and declare it to you."
God is mysterious. We have to accept this fact. We cannot think that we can completely understand God.
Most people know there is a God. Some people even experience that God is present, loving, and/or personal. Others only sense God as a force. Those people who are aware of God as a person know they can reject God by sinning. They sometimes know when they're not at peace with God. Then they feel a need to get right with God, to be justified (Rm 5:1). Few people experience much more of God than this, but there is much, much more of God. Jesus said to His disciples: "I have much more to tell you" (Jn 16:12).
God is Trinity, three Persons in one God. God is a family. God has become a human being. This God-made-Man is Jesus, Who is fully God and fully Man. There is so much more to God than our experiences. The holiest saints who have ever lived have only just begun to know God. "Eye has not seen, ear has not heard, nor has it so much as dawned on man what God has prepared for those who love Him" (1 Cor 2:9).
On this Trinity Sunday, may we devote more of our energy to developing as deep a personal relationship with the Trinity as possible. While we cannot even begin to fathom the mystery of God, we do know that he is always with us. The gift of faith that we have received at our baptism helps us to live in his presence and know that he is always with us.
