The Church of England has survived the Spanish Armada, the English Civil War and Elton John performing “Candle in the Wind” at Princess Diana’s Westminster Abbey funeral. So it will probably survive the note the Vatican issued last week, inviting disaffected Anglicans to head Romeward, and offering them an Anglo-Catholic mansion within the walls of the Roman Catholic faith.

But the invitation is a bombshell nonetheless. Pope Benedict XVI’s outreach to Anglicans may produce only a few conversions; it may produce a few million. Either way, it represents an unusual effort at targeted proselytism, remarkable both for its concessions to potential converts  married priests, a self-contained institutional structure, an Anglican rite  and for its indifference to the wishes of the Church of England’s leadership.

This is not the way well-mannered modern churches are supposed to behave. Spurred by the optimism of the early 1960s, the major denominations of Western Christendom have spent half a century being exquisitely polite to one another, setting aside a history of strife in the name of greater Christian unity.

This ecumenical era has borne real theological fruit, especially on issues that divided Catholics and Protestants during the Reformation. But what began as a daring experiment has decayed into bureaucratized complacency  a dull round of interdenominational statements on global warming and Third World debt, only tenuously connected to the Gospel.
