Those disaffected Anglicans in England and Wales who think they can take up Pope Benedict's offer and switch to Rome with a "pick and choose" attitude should think again, the Catholic Archbishop of Westminster, Vincent Nichols has said.

Many Anglicans unhappy with women's ordination and gay clergy cannot just convert to Roman Catholicism as a way out, but must accept Catholic doctrine  wholeheartedly, he said.

"Nothing is envisaged in this provision that the Pope has put in place is a kind of minimalist approach to picking bits of the Catholic faith that I like and then seeing myself as it were contained as a quasi-Catholic, not a real Catholic, under the umbrella of this constitution," he said, referring to a "buffet approach" to the faith that some Catholics dismiss as "cafeteria Catholicism."

It is still unclear how many Anglicans will convert, but the invitation, in the form of what's called an Apostolic Constitution, has opened up old wounds between the Vatican and Lambeth Palace.

It has also crystallised divisions within the Church of England, the Anglican mother church.
