It has been said so many times that one can only conclude that fundamentalist malice is the only reason this particular slander is perpetuated.
Catholics worship the Christian God. They say the Nicene Creed and the Apostles Creed, neither of which have a word of Mary-worship in them.
What Catholics do is to turn to Mary, and to others (saints) they believe are with God in heaven, and they ask them, as friends of God, to intercede with the Deity on their behalf. It's something along the lines of having a friend in a royal court who can obtain favours from the king.
What Catholics do not do is to worship these saints - not even Mary. They venerate them, and they venerate Mary in a particular way because of what the Bible says about her and her unique relationship with God. It could be argued that the Orthodox have much the same, if not even more intense veneration of Mary.
Now JP, you have a lot of learning and reading to do. You should attend a Catholic Mass and see if there is a word of worship of Mary or the saints. All you will hear is that respect is shown to her and her intercession with God is invoked.
Your Protestant malice is very much on view here. And as with most malice it is founded on untruth and lies. So much for your Christianity.
BTW, I am agnostic, but I reverence the truth above lies. Satan is the Father of Lies, and you are very close to him, by all appearances. Take care for your soul, if you have one!
