That depends entirely on how you are defining "worship." If you are using the word "worship" as most protestants in the English speaking world currently use the word, you are referring to the adoration that is due to God alone. In that sense of the word, Catholics worship God, and only God. As He is the only Divine Being, our Creator, and Eternal, He is the only thing worthy of Adoration. Catholics call this latria. So to answer your question, in that sense of the English word, worship, Catholics worship nothing besides God.

.Catholic AnswerGood, sincere Catholics worship God everywhere for the simple reason that we are to worship Him with our entire life, we are to pray always, we are to take up our cross daily, and follow Him.
