1. The most traditional and popular explanation of the Trinity is St. Patrick’s description
The Trinity is like the cloverleaf with three separate sections yet part of the same leaf.
I arise today
Through a mighty strength, the invocation of the Trinity,
Through a belief in the Threeness,
Through a confession of the Oneness
Of the Creator of creation
St. Patrick (ca. 377)
2. I like this modern analogy, which I read about decades ago and never forgot
The Father is the light bulb on the ceiling; the source of all light
the Holy Spirit is the wiring which connects the Almighty with us on earth and
Jesus is the light switch; the way we activate our connection to God.
3. Someone left a comment on my blog three years ago and this is my favorite analogy of the Trinity.
Picture a glass table with a three-legged stool sitting on top.
Taking in the scene we can see the entire stool and understand that it is one piece of furniture with three legs.
However what if a young child was blindfolded and then guided to sit under the table. This child has never seen a stool.
When asked what he can see when the blindfold is removed and without moving his head or his eyes, he would describe three flat, separate circles.
Now try explaining to him that a three-dimensional object rested on his ceiling.
We are that toddler who cannot grasp what we cannot see with our naked eyes.
