Does the 1962 rubric require the priest to proceed directly in a straight line, etc.
Please regard me as inspired, but not to be taken
literally. My intended point was that the NO altar will serve as an obstacle. The priest and altar servers will have to allow for it in their movements and it will likely block the view of Mass attendees. It is either stupid or malevolent for the diocese to put the Latin Mass in such a configuration.
