“If the idea of God as both Three and One seems far-fetched and obfuscating, look in the mirror someday. There is (a) the interior life known only to yourself and those you choose to communicate it to (the Father). There is (b) the visible face which in some measure reflects that inner life (the Son). And there is (c) the invisible power you have in order to communicate that interior life in such a way that others do not merely know about it, but know it in the sense of its becoming part of who they are (the Holy Spirit). Yet what you are looking at in the mirror is clearly and invisibly the one and only you.”She pointed out that we relate to God mostly through His creation, through the mountains, oceans, valleys, trees, raindrops - seeing the vast plan and organization at work, on a daily basis.
And we are told to look for the face of Christ in every being, seeing the Divine in the face of a baby laughing, a homeless man needing food, a mother whose children have all just gone to sleep and there is peace in the house, and a son whose father has just asked him the same question for the 50th time that day because of the dementia of Alzheimer's. As we learn in Matthew 25:40: "Truly, I say to you, as you did it to one of the least of these my brethren, you did it to me."
The Holy Spirit is what aids our awareness of the Divine throughout all of creation, that allows us to see the face of Christ in our fellow man, that reminds us of the greatness and magnificence of God, which is only reflected in His creation.
So, will you honor the Trinity through this experiential mystery? Allow the Holy Spirit to help you see? Look in the mirror, and begin there - knowing that every person you see has that same capacity of seeing the Trinity within their own face.
