Joseph, your ignorance of what the Catholic church teaches in enormous, but very typical......first off, the church is on earth and in heaven. We ask saints to pray for us just as we ask other people to pray for us in our time of need. Have you ever heard of a prayer chain where people are asked to pray for a sick person or someone in need? Catholics ask saints to pray fro us too...why not? The bible says the prayers of the righteous are more powerful, and who is more righteous than those in heaven?
Catholics do not worship saints, Mary or statues. We do not place saints with an equal status of God.
Pick yourself up a Catechism of the church and read yourself what the church teaches instead of making a fool of yourself.
