They did the same thing to the renovated chapel/altar in Ecône a few years back.
Are they trying to comply with the 2002 General Instruction for the Roman Missal (Novus Ordo), for which the versus populum posture is the norm?
“The altar should be built separate from the wall, in such a way that it is possible to walk around it easily and that Mass can be celebrated at it facing the people, which is desirable wherever possible."[18]Where practicable, the church altar should be built in such a way that the priest can easily walk around it and can celebrate Mass versus populum, but the text does not oblige the priest to avail of these possibilities.[19]”http://www.liturgyoffice.org.uk/Resources/GIRM/Docuмents/GIRM.pdfSomewhat worrisome that construction projects at two of the principle SSPX churches feature such altars.
A cօռspιʀαcʏ theorist might construe this architecture as another incremental preparation for an eventual hybrid Mass.
They’ve already got worldwide dialogue Masses, congregational singing, and now their largest church in the Western Hemisphere seems set up for versus populum Masses, should that be desired in the future.
Outside of the altar, the church is beautiful.
