Saint Irenaeus said where the Spirit of God is, there is the Church. We believe there is only one earthly Church (“I believe in one, holy, catholic and apostolic church” – the Nicene Creed). We know where the visible Church is, but we cannot know for assurance where the Spirit of God may or may not be outside ‘the one, holy, catholic and apostolic church’! Orthodox Christians must not therefore presume to pass judgment on non-Orthodox Christians or their communities, think or speak triumphalisticaly about the Orthodox Church, but rather strive to live out their faith without compromise, in humility and repentance.
