Person

God is one Being existing in three Persons.

For me, "Being" is easy to understand. One what. That what is God. The essence of God is one. But "Person" is where I have trouble explaining to people, so in this post I hope to type out my understanding of "Person" to hopefully get my thoughts straightened out.

First, in reference to each Person of the Trinity, each are referred to as a who. Namely the Father, Son and Holy Spirit. Three who's of the Trinity.

Second, in saying that the Father, Son and Holy Spirit are Persons is to say that they are each personal. They have a personality of their own, distinct from each other. What makes them a "Person" is that they are personal. All three Persons can be grieved, be lied to, speak, etc. And in speaking, they refer to themselves as "I" and "me." In contrast, a rock that contains the being (essence) of a rock is not personal as it cannot interact personally to other persons.

So in the one Being (essence) of God, there exists distinctively three divine personal who's (Persons). The Father, Son and Holy Spirit. And all three share completely the one divine Being of God.

And that is as far as my mind can wrap around it.
