Isaiah 48:16 — Come ye near unto me, hear ye this; I have not spoken in secret from the beginning; from the time that it was, there am I: and now the Lord God, and his Spirit, hath sent me.

There are things in this faith of ours that seem (more or less!) simple. There are other things that we will never fully understand, but about which we can only know and understand more. One of those matters is the business of the Holy Trinity.
When I wrote my first piece about the Trinity, last month, I quoted the Moody Handbook of Theology as saying (in part), “Human reason, however, cannot fathom the Trinity, nor can logic explain it, and, although the word itself is not found in the Scriptures, the doctrine is plainly taught in the Scriptures.” It should be clear then that what I offer here is offered, in humility with no claim of certainty.
The view of the Trinity is one of those things that separates a Western and Eastern Christianity. In the West there is (at least) an implicit acceptance of an Augustinian view of a hierarchy in the Trinity — the Father somehow (inexplicably) superior to the Son and the Son somehow (inexplicably) superior to the Spirit. In the Eastern (Orthodox) tradition the Trinity is a community giving and receiving love, sharing in each other’s presence and work. the Father, the Son and the Holy Spirit are three distinct persons sharing one common reality.
I’ve seen a suggestion recently that really resonated with me. It follows more of the Eastern view. It carries with it the idea that the Trinity is an open community, accepting each of us into the family. Somehow it seems to be in the spirit of a scripture that I love:

Neither pray I for these alone, but for them also which shall believe on me through their word; That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me. And the glory which thou gavest me I have given them; that they may be one, even as we are one: I in them, and thou in me, that they may be made perfect in one; and that the world may know that thou hast sent me, and hast loved them, as thou hast loved me. (John 17:20-23 KJV)

My mind ran on these thoughts a little in church today. A sweet couple came with their twin daughters to dedicate them and commit to bringing them up so they might come to know Christ as soon as may. Then we sang Paul Baloche’s song, “Our God Saves”, which starts:

In the name of the Father, in the name of the Son
In the name of the Spirit, Lord, we come
We’re gathered together to lift up Your Name
To call on our Savior to fall on Your grace

Our church, under God, is a community of believers open to any that will come to it sincerely seeking God. It is, I believe, our joy to seek the presence and filling if the Holy Spirit. It is a precious communion.
