Roman Catholics practice idolatry, “The worship of idols, images, or anything which is not God.”[1]
They state that, “As the Blessed Virgin has a separate and absolutely supereminent [sic] rank among the saints, the worship paid to her is called hyperdulia.”[2] Honour given to saints is called “dulia,”[3] and is a kind of worship.[4] Roman Catholics also worship objects: “. . . Worship according to the following definition: homage paid to God, . . . or even to the objects which have a special relation to God.”[5]
Roman Catholics don’t view worshipping of Mary, saints, or even images as idolatry; because, to them idolatry “Is giving to creatures the worship which is due to God alone.”[6] They call this highest kind of worship “latria.”[7]
Christians do not worship angels or saints or objects. Look at what the angel said to John, writer of the Revelation, when John fell down to worship him, “See thou do it not . . . worship God.“ (Rev 22:9) As far as I can see, assuming that John didn’t try to worship the angel as God, the outcome is clear; Roman Catholics (at least those who worship images, saints, etc.) are sinners; because, they worship things the Bible indicates we aren’t to worship.
