And their intention is to work together to perfect us in love. This basic Trinitarian model or framework helps us to explain and discuss the experience of Christians everywhere for two thousand years. Obviously God is much bigger that any of our explanations, and many people experience and love God without getting the explanation right. You can drive a car very well without having a clue about the ignition, transmission, or power brake systems. Though the task of preachers is to proclaim the very good news of the love of God for us as Father, Son, and Holy Spirit, things can go badly wrong in three ways.
Some theologians try to deny our Trinitarian model.
And that inevitably moves them into another religion. Some bigots make additions, require people to believe them if they want to be church members, and excommunicate all others. The result is that honest people are forced to quit church going rather than put up with this insult to their intelligence. By way of example we note the simplicity of the Nicene Creed declaration about the death of Christ. We all agree that Jesus' death on the cross was a sacrifice of supreme importance for our eternal destiny.
