It isn't an emphasis. It is simple non-Christianity. We've been worrying that Pope Francis isn't Catholic. The Bear must wonder if he is even Christian.
I'll agree with one of those interviewed that it is disturbing to hear people speak of ad orientem worship as though it might be harmful, or divisive, while nothing could be more Catholic in both the narrow - as in regards the faith - and the wider - as in universal - aspects of the term.
I have written and said it enough times: Bergoglio is an avowed enemy of the faith! When I first started saying it I was alone. Nowadays, I don't even bother to say it because anybody who has been following him and loves the faith is of the same opinion.
