They seem to worship the created not the creator of the universe.
The key word there is "seem." No serious Catholic thinks images of the saints or Jesus are the actual "real deal." No saint has power of their own, other than that of their prayers. All is done in accordance with the Will of God.
The real issue, and the truth, is that post-Luther Christians worship God only by word and song, when higher worship, the Divine Liturgy (or Mass in the Western Christian tradition), is due the Holy and Undivided Trinity.
They know the difference. Much as we like the idea of the BVM for bringing it down to our level where we can comprehend things, we know where the real power is.
