Yes, the God whom we worship, we worship as a Trinity. We worship the one God as the Father, Son, and Holy Spirit, because that is how God has chosen to reveal himself to us. For those of us who have the need to know and explain this is a difficult thing. Because ultimately we cannot explain God.
Ultimately we come to the point wherein we have to acknowledge that God is a mystery to us—a mystery that we can only understand to the extent that He chooses to reveal himself to us.
And, yes, in writing this, I am quite mindful that there are some among us who may well take umbrage with my use of the masculine pronoun. To be sure, God is a spirit. Therefore God is sexless. But God invented sex, and he invented us as beings who are conscious of masculine and feminine pronouns. English, as best as I know it has not evolved to such an extent as to include a suitable neuter pronoun that conveys personhood.
What should I write? God is a mystery that we can only understand to the extent that it reveals itself to us? Well, what that conveys is the depersonalization of God. My computer is an it—and I most assuredly don’t worship it.
God is a mystery that we cannot explain. If we could explain God, then God would not be worthy of worship. Humans do not worship that which can be explained in human terms. So maybe it is a valuable lesson for us here, that once a year we stumble around this challenging and incomprehensible language about God. It forces us to recognize and allow for the reality of mystery in life. And in the times in which we live, that is not altogether bad.
