She is worshipped\venerated all right. One of my theological professors from seminary visited a Catholic church in France which featured a huge cross inside with Jesus dying on one side and Mary on the other.
Jesus was sinless. Catholics say Mary was. Jesus ascended into heaven. Catholics say Mary did. Jesus is our redeemer and mediator. Catholics call Mary co-redemptrix and co-mediatrix. Jesus was God. Catholics call Jesus the "Mother of God." And when pictured with Christ, they almost always show her as an adult and him as a baby, implying her superiority over him.
Some of this non-biblical Mariology did not become dogma until the last 50 to 150 years. But Catholics pray to Mary far more than to Jesus, despite the fact that not one verse in the New Testament supports this. And Mary is not the Mother of God. There has never been a time in eternity past that the Son was not God. Mary is the mother of Jesus' human body and human nature only. And Christ was offered as a sacrifice once for all according to Hebrews chapters 8-10, not continually sacrificed and eaten in the Supper. Roman Catholicism since its beginning in the fifth century A.D. has become a mixture of some Christian doctrine, some pagan doctrine, and whatever else happens to appeal to enough Catholics and their popes. I appreciate the anti-abortion and anti-homosexuality stands of this current pope. But all of that could change at any time with some Papl declaration. And the leniency with which all of these homosexual priests have been treated makes me wonder how serious the RCC is about its anti-homosexuality stand.
