First there was the Rome visit in September by the Russian Orthodox Archbishop Hilarion of Volokolamsk, Moscow's man for ecumenical relations. In high-level meetings, both sides argued that their shared resistance to secularism and moral relativism calls forth a further rapprochement of Orthodoxy and Catholicism. Declaring that "More than ever, we Christians must stand together", Hilarion insisted that each side can appeal to shared traditions and work towards greater closeness in a spirit of "mutual respect and love".

That this was more than diplomatic protocol was confirmed by the Catholic Archbishop of Moscow, Monsignor Paolo Pezzi. In an interview with the Italian newspaper Corriere della Sera, he said that union between Catholics and Orthodox "is possible, indeed it has never been so close". The formal end of the Great Schism of 1054, which has divided the two churches for a millennium, and the move towards full spiritual communion "could happen soon".

Even on doctrinal matters, Roman Catholicism and Russian Orthodoxy are essentially in agreement. Hilarion acknowledged that the two have different ecclesiological models, with the former favouring a more centralised structure led by the pontiff while the latter emphasises the autonomy of provinces and local churches. "There remains the question of papal primacy and this will be a concern at the next meeting of the Catholic-Orthodox commission. But to me, it doesn't seem impossible to reach an agreement", said Pezzi.

Indeed, when Joseph Ratzinger was elected pope in 2005, one of his first acts was to drop the title of patriarch of the west. Rather than affirming absolutist papal supremacism, Benedict indicated with this act that he seeks to blend the historical primacy of the see of Rome and the pope's universal jurisdiction with that of local churches in east and west. The next step for Rome is to incorporate the Orthodox emphasis on conciliarity as a counterweight to papal authority. Increasingly shrill attacks on Benedict by Catholic dissidents like Hans Küng represent little more than the angry expression of some liberals who are excluding themselves from pan-Christian reunification.

Meanwhile, closer church ties will be greatly helped by concrete co-operation. There's already considerable convergence on social teaching, as evinced by Kirill's preface to Cardinal Tarcisio Bertone's book The Ethics of the Common Good in Catholic Social Doctrine. Both Catholicism and Orthodoxy argue for a civil market economy embedded in communal relations and serving the public good rather than exclusively private profit, a prominent theme in Benedict's recent social encyclical "Caritas in veritate".

Similarly, last week's Rome visit by the Archbishop of Canterbury has advanced Catholic-Anglican relations. Far from humiliating the primate of the Anglican Communion by parking papal tanks on the lawn at Lambeth, Benedict emphasised the importance of Anglicanism in promoting the unity of all episcopally-based Christian churches.

The presence of Anglicans within Catholicism might lead to a better appreciation of Anglicanism's unique contribution to Christianity. It could also help Anglicans define an episcopal identity beyond the divide between liberals and evangelicals.

No less 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.
