The first and deepest mystery of the Christian faith is the Trinity.
It is a mystery because we can never fully understand it: we have 3 distinct Persons in One God. The Father is not the Son, neither of Them are the Holy Spirit, but They are all one in Being and thus only One God.
Some people become very uncomfortable talking about the theology of the Trinity because it bends the mind and tries to put an infinite mystery into the finite human brain. But as mysterious as this is, the Trinity is the only mode of being that could exist if God exists.
This is based on two things that exist in the universe: persons and love.
