One in Being

...the only Son of God, eternally begotten of the Father, God from God, Light from Light, true God from true God, begotten, not made, one in Being with the Father.  Through him all things were made.                                                                                                 Nicene-Constantinople Creed

 In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things came to be through him, and without him nothing came to be. John 1:1-3

The Trinity falls into the area of "things too wonderful for me" to understand. What I do get is that God is Love and there is a logic to the assumption that in Love there must be a lover, a beloved and the love that passes between them.  The Son, the Word is the beloved part of the one Love. 

Obviously, as John 1 shows,  Christians were clear on the "One in Being" part by the beginning of the second century AD. 

Maker

We believe in one God, the Father, the Almighty, maker of heaven and earth, of all that is seen and unseen. Nicene-Constantinople Creed

Here's the easy one, the beginning of what I believe: Wake up. Look around. Wow--who made this? 

For this part the Baltimore Catechism hit it just right. Who is God? God is the supreme being who made all things. Who made me? God made me.   

Then it gets complicated. Why did God make me? He made me to know, love, and serve Him in this world and to be happy with Him in the next. 

I was twelve when I asked the question, "Is there a God? Because if there isn't this religion thing doesn't make much sense." The experience that followed the question is hard to describe.  What it left me with was the sure knowledge that God is and that He is the hub around which my existence revolves. He is the centering reality that gives form to my life.  Everything else is secondary.
