Redemptoris Mater Chapel; a barometer of the liturgical shift? Part II.

Gregor Kollmorgen of the New Liturgical Movement has a fascinating piece on the subtle shift taking place in the Redemptoris Mater Chapel year by year. The link is "photo dense." His text reads, in part:

[...]

While the pictures may not be optimal for this purpose, we can still see that a further step has been taken: the Cross, which had remained off-centre last year, has now returned to its traditional place in the centre of the altar.While this is admittedly not ground-shattering news, and this ad orientem setup of the Redemptoris Mater chapel has, as far as I can see, not (yet) been used for Mass celebrated there that we know of, it may still serve, as the headline, which is Shawn's original headline of last year's post, suggests, as an indicator of the slow but steady and long-term reorientation of the liturgy which the Holy Father is bringing about...

One must see the progression of photos to see the point being raised by Killmorgen: namely, that there is a transition taking place for an ad orientem celebration of Mass. Finally, the comments of the Holy Father at the end of this piece concerning concelebration are very interesting.
