Draw a circle on a piece of paper. Go on, gentle reader, just indulge me for a minute or two. Any piece of paper will do, any poorly drawn circle.
This circle represents the unity of God. As you learned in geometry class, even though there are only 360 degrees in a circle, there are an infinite number of points on it.
Now put three dots, three points, anywhere on your circle.
These are the points of reference that Christian theology refers to as “Trinity”. These points can be anywhere on the circle but if you draw a line between each point and the other two you will notice that, no matter where you positioned them to begin with, they are always in a triangular relationship with each other.
Alternatively, should you begin with three random dots on your paper, and the lines between them, you will also discover that this triangle, however you have draw it, will always be on the same circle; they will always share the same unity.
A triangle is the only multi-sided shape for which this is always true. It is easy to draw a four-sided shape whose points cannot be connected by a circle; you can also draw a five-sided shape for which this is not true; a six, a seven, and so on. But you can never draw a triangle whose points do not share a circle between them.
A “Trinity” of points always shares the same unity.
The scriptures tell us some things about each of the points of the Trinity, also in relation to the others. But they don’t tell us everything. God is an unbounded mystery. The locations where the divine is revealed are infinite. The words we use to describe these points are only as confined as our vocabulary, reflecting our era and culture, showing up the limits of our language and experience.
