In the past two months, relations between the three main Christian churches have moved in more promising directions than perhaps during the past 50 years of uninspiring liberal dialogue. By opening a new chapter of theological engagement and concrete co-operation with Orthodoxy and Anglicanism, Pope Benedict XVI is changing the terms of debate about church reunification. In time, we might witness the end of the Great Schism between east and west and a union of the main episcopally-based churches. Indeed, when Joseph Ratzinger was elected pope in 2005, one of his first acts was to drop the title of patriarch of the west. Closer church ties will be greatly helped by concrete co-operation. Last week's Rome visit by the Archbishop of Canterbury has advanced Catholic-Anglican relations. Benedict emphasised the importance of Anglicanism in promoting the unity of all episcopally-based Christian churches. Significant was the fact both the pope and the archbishop spoke in favour of a different model of socio-economic development that does not rely exclusively on the state or the market. Rather, it accentuates mutualist principles of reciprocity and gift-exchange and the absolute sanctity of human and natural life which is relational, not individualist or collectivist. This shared social teaching is key in further developing concrete links and bonds of trust among Christians of different traditions. Moves towards church reunification are signs of a revivified Christian Europe, one which can use its shared faith to transform the continent and the whole world.
