The language the church uses to speak about God is often difficult. Some people say that developing a complicated doctrine of God as Father, Son and Holy Spirit hides the simple faith of Jesus. It obscures (they say) the basic teaching that “God is love.” Preachers have been known to satirically quote the (mainly unused Athanasian Creed from the old prayer book: “The Father incomprehensible, the Son incomprehensible, and the Holy Spirit incomprehensible” and add “the whole blooming thing incomprehensible.”
Certainly that echoes the feelings of a great many Christians who use the language in worship, but (often secretly) feel baffled by it. But I suggest it’s well worth persevering with it.
First, consider the simple statement “God is love.” Our simple experience of love is that it is about relationships. We show love to someone, know ourselves loved by someone, feel love for someone. Love is a verb, a doing word, before it is a noun or naming word. So how can God actually be love, rather than just being loving to us, others, the world?
The answer the church gave to this question took its shape from the experience of Jesus. The first Christians experienced the presence of God in Jesus, yet saw Jesus praying to his Father, and teaching them to pray “Our Father.” They experienced God acting as Spirit in their life together: yet this experience of God was not the same as Jesus, but instead helped them know the risen Jesus. So they started to talk about Father, Son and Spirit at the same time they were teaching and living out the idea that “God is love.”
They could say “God is love” because there was, as it were, a set of relationships at the heart of God’s being. God did not just enter a loving relationship with the world, did not just show love, as an individual might, but actually was love – an eternal loving relationship.
God does not just invite people to love him, but to join in an already existing relationship of love, just, as it were, in ideal circumstances, a child is born into an already loving family. And so we usually begin our worship and prayer with “In the name of the Father, and of the Son, and of the Holy Spirit.” We don’t start from scratch, we join in the love that’s always been going on, always is going on, and always will go on.
