Eastern Orthodox Comment on Division & Unity

Given that I am Orthodox, I can't follow Leithart's vision for the future of the Church. But the notion that the unity of Christians is unacceptably utopian and that Christian division is something to be celebrated is foolish. Christians believe in more than contingent historical circumstances cementing division. Christians believe in the immanent providence of God, animated by the Holy Spirit, who overcomes the sin of man in order to create a new humanity in Christ: and Scripture absolutely reviles disunity. That there is disunity doesn't entail that we should be reconciled to it, any more than pervasive sexual immorality entails that we should reconcile ourselves to it because of the sinful tendencies of fallen man.
