From a reader:
What is the significance of the ambo being elevated? Should it be as high as the altar? What should their positioning be relative to one another? I ask these questions, because I recently made the statement that if one had to pick between the two, it would be better to have the altar elevated rather than the ambo. I was challenged fairly convincingly that this would degenerate the Liturgy of the Word, which is in fact just as important to the mass as the Liturgy of the Eucharist. Who was right?
I suppose the ambo is elevated so, practically, it can be more easily seen.
However, if there has to be a choice between elevating the ambo or the altar, I would answer that the altar should be elevated.
This doesn’t, of course, rule out very high pulpits, as in older churches.
I am not sure if any official documents of the Church address this issue. Perhaps some readers will know.
