Your words were not, "A poster here believes Mary..." You were assigning it to the Catholic faith. Now you know that Mary as mediator is not Catholic teaching. Further, as I was attempting to point out in other of your posts, changing the word clarifies much. How you or I may define 'mediator' as used by scripture, the word mediator can have secular meanings as well. The poster could well have meant/used emissary, advocate, or a dozen other synonyms, but you chose to jump on the Biblical use of the word Mediator as it applied to Christ and further proclaimed that's how Catholics see Mary--that Catholics worship Mary! Leave what Catholics believe about Mary to Catholics to explain, while reminding yourself you can note what your sect believes about Mary.
