Much ink has been spilled on the doctrine of the Trinity and rightfully so. The theology of the Trinity is an important and beautiful and formative doctrine that is at the very heart of what it means for us to be Christian.
Here is a great quote by Bishop Kallistos ware on the Trinity (you can also find a youtube video of B. Ware talking about the Trinity.)
"There is in God genuine diversity as well as true unity. The Christian God is not just a unit but a union, not just unity but community. There is in God something analogous to “society”. He is not a single person, loving himself alone, not a self-contained monad or “The One”. He is trinity: three equal persons, each one dwelling in the other two by virtue of an unceasing movement of mutual love.”
— The Orthodox Way, by Kallistos Ware
The icon above is Andrei Rublev classic rendering of the Holy Trinity or as it is properly called, The Hospitality of Abraham.
May this icon lead you into deep prayer and contemplation because you have been invited into the very life of God!
