There is/was a very long thread that started with someone quoting a Catholic who stated that Catholics worship Mary. I didn’t read the whole thread–way too long! So, maybe someone brought this up, but if not, it needs to be said for the sake of clarity.
If a Catholic says we worship Mary they are using an older meaning that used to define it as, in this context, simple veneration not the adoration due to God alone.
What we mean by worship these days is the adoration of God, which is what it means to most people, although the dictionary gives more than one definition, including veneration, which is not the same thing in Catholic theology.
When we offer worship we are offer sacrifice to God. We offer God the sacrifice of our prayers and praise, of course, but for us it goes beyond that to the offering of the Sacrament of the Altar, the Eucharist. For us, no true worship is complete without it. It’s why we join all our prayers and praises to the Sacrifice of the Altar, as we put it.
So, Mary is not the object of worship for us. We offer her veneration of the highest order (or hyperdulia), and ask for her intercession (as a part of the Communion of Saints), but not worship in the sense our Protestant brethren mean–or we mean these days, either.
Ergo, Catholics do not worship Mary–not in the modern sense of the word.
Sorry for the long post, but such important things can’t be explained in one sentence–I apologize for not being more concise, but that’s as concise as I can be.
