The saints in heaven offer our prayers and petitions to God, as we sometimes ask them to do.
the four living creatures and the twenty-four elders fell down before the Lamb, each holding a harp, and golden bowls full of incense, which are the prayers of the saints. (Rev. 5:8)
Well, then, Catholics, in asking saints to do things for them, are praying to the saints as to God, in spite of another poster’s claim that it is not so.
