Christ is ascended!
He's not infallible, so they can throw out anything he says whenever what he says is inconvenient.
I know that according to the Orthodox diptychs of the Catholic Church, he is not, but he is a bishop of Rome, if we are going to use that title for all ecclesiastical communities. Like we call the Episcopalian bishop of Chicago "a bishop of Chicago." Just not a bishop of Chicago like the 3(?) Orthodox bishops of Chicago (we have more, but the others have their titular sees elsewhere).
According to your Ecumenical Patriarch, His All-Holiness Bartholomew, Benedict XVI is "His Beatitude, the Bishop of Rome." Not "layman of the Vatican", as you would prefer to call him. If you have a problem with that, take it up with His All-Holiness, not with me.
If His All Holiness commemorates your supreme Pontiff, His All Holiness is who will be thrown out.
So, are you admiting that you believe everything your supreme pontiff says is infallible?
Btw, I do believe that HAH refers to Rowan Williams as Archbishop of Canterbury, but if Abp. Rowan was received into Orthodoxy, it would be as a layman.
