I don’t doubt that what you said. The left could infiltrate cause problems and take over like they always do.
But like someone else suggested, they would have to get through the Pope to do any real harm, so just like leftist Catholics who try to wreck the Catholic church, leftist Episcopalians and Anglicans will not get far if they try to do this.
They already have what they want -- homosexual bishops, 'unions', female priests and bishops, abortion on demand, no Magisterium, and nobody in charge (except them). And pretty vestments.
Plus the leftists are suing for and obtaining (in most cases - Virginia being a notable exception and California a possible one) the property of the orthodox believers who are leaving. It's the money and the power they're after, and the gorgeous buildings. People talk about the wealth of the Catholic Church, but they have absolutely no idea how much the Episcopal Church is worth. Just ONE example - a TEC parish in NYC has sold air rights to surrounding office buildings and they are rolling in hundreds of millions of dollars.
What I'd really like to see is for His Holiness to offer a straight trade to the Anglicans. We'll take the high churchers, they can have the happy-clappy 'reformers', the Chittisters, O'Quinns and all the rest of the crazy feminist 'sisters', the Haugen/Haas liturgists, assorted heterodox professors at Notre Dame and Georgetown, and any Liberation Theology Jesuits that are still breathing.
It's such a good deal for us, I don't think they'd take it.
