They are different “denominations”. We can agree about the fundamental ideas at the centre of Christianity. But we differ in our detailed theological approaches, our traditions and our practices. If anything, different denominations are proof that Christians are free thinkers. We admit with sadness that Christians often went wrong because of these different approaches, refusing to accept diversity. However, there are now strong ecumenical movements, which try to find common ground amongst Christians and which have made huge progress over the last 100 years or so.
