In 1188 the Archbishop of Canterbury, Baldwin, visited his Welsh diocese.
As his guide and companion he chose Master Gerald de Barry.
Gerald's father was a Norman settler who took the name Barry from an island near Cardiff.
His mother was the daughter of a Welsh princess and a Norman freebooter.
In his diary of the Welsh tour, Gerald mentions the Welsh custom of eating meals in groups of three "in honour of the Trinity, having learnt the custom from early Christian missionaries."
As we celebrate Trinity Sunday, the only Sunday dedicated to a Doctrine— or Teaching— rather than an Event, we begin a series on the One God whom we know as Father, Son, and Holy Spirit.
Although God is ultimately unknowable, there are some things that The Sacred Three have revealed to us, and therefore some things we do know.
1. God is. God does not exist.
"Existence" is a word for us, for the creation and creatures whom God has created.
Although as creatures, we exist in certain places and certain times, God is beyond all places and all times.
Recognizing this, the twentieth century Christian author and theologian Charles Williams suggested that the beginning of the Lord's Prayer should be changed from "Our Father in heaven" to "Our Father in whom is heaven!"
2. God is Transcendent— God is beyond everything we experience and know*
3. God is Immanent— God is present in and permeates Creation**
4. God is Personal
We are persons, and God created us in God's image.
God became one of us in the person of Jesus.
God is a unity of three Persons— Father, Son, and Holy Spirit; in other words, a Trinity.
Tomorrow: the Progressive Revelation of God's Being
* If God's Transcendence is pushed to the extreme, the result is Deism— God is so utterly beyond everything that God is uninvolved in the Creation.
** If God's Imminence is pushed to the extreme, the result is Pantheism— God so utterly permeates Creation that God and Creation are fused and without distinction
