Some bishops are fighting the Holy See’s norms for liturgical translation and the most recent draft prepared by the reconstructed ICEL. They essentially think that the language is too hard, which implies that they think people are not very smart.
Thus, words like "ineffable" are "unspeakable" in the Mass. They are tooo haaard!
This applies also to "gibbet". No one could ever understand what "gibbet" means!
So, visual aids are often helpful for liturgical catechesis … and basic English vocabulary.
