Adding a new altar in front of a magnificent older altar and placing the new altar much lower than the old creates eye disorientation. Which is the most important piece of furniture in this cathedral? Most people religious or not would say the old higher altar—that which is highest is the most important.
But with the addition of a post Vatican II free standing altar placed at the lowest spot in these two photos, the hierarchy of importance becomes three-fold with the most important now the least important.
In these photos, intuitively ones knows that the high altar the most important; next would be the bishop’s throne and the various chairs strewn about three steps lower than the high altar and three step higher than the low altar and of course the least important is the free standing altar.
