I think there is a somewhat disturbing trend in the church today of completely confusing the Trinity.
I remember learning the lessions in children’s church that the Trinity is like an egg. In order to have an egg, you need a shell, a white and a yoke. None of the component parts are themselves a egg, and you can not have an egg without all three. If we use that analogy then the church is making scrambled eggs.
When you ask a child in almost any Sunday school, “Where is Jesus?” Most (of those who answer) will say, “In my heart.” But that is not biblical, Jesus is at the right hand of God the Father (1 Pet 3:22, Heb 12:2 among others). The Holy Spirit is the one sent to live in us.
When we pray, to whom do we pray? The examples of prayers we have in scripture are all to the Father. So often you hear prayers that start out to Jesus, “Dear Jesus,” shift to the Father, then drift to who knows where. Jesus said that we ought to pray to the Father in His name (John 15:16).
Maybe I’m nitpicking, but that is at least one thing I know I am good at. I also do not completely understand all aspects of the Trinity because the bible does not get into deep theological discussions about it. So that leaves us to endless debate about the exact roles of each. But at least we should get the obvious things right.
