I'll be honest, I've often struggled with the Trinity. Not because I didn't believe it or accept it - I've always seen the logic in saying that there can only be one God, so if we believe in Jesus as Divine and also in the Spirit, then the Trinity - three persons but one God, makes sense. But it was always for me a kind of theoretical meaning. It was a belief, a teaching, a dogma, not something that really moved me.
And then I heard an explanation that clicked with me and started to make a difference not to my belief, but to my prayer. It is an old explanation, but somehow now it just clicked. It goes like this. God is Love, so St John says. He doesn't say God loves, but he says God is love. Now the thing about love is that it is not just a feeling, or an idea, but an action. For there to be love there needs to a lover and a beloved, as well as the power of love itself.
And suddenly the Trinity starts to make real sense. God is Love because God is community, three in one, Father, Son and Holy Spirit.
And love cannot be selfish. To love is to give. And God’s love, real love is so powerful that it overflows into his creation.
God loved the world so much that he gave his only Son. And because God is love he gives himself to us. The love we know in this world is just a pale reflection of that wonderful love of God. That is what the Trinity is all about.
