One of us is in serious violation of the ten commandments.
If you're right, then I'm worshiping a different god or statues; idols; I'm bowing down before something I consider a god; Mary is being worshiped by me...
If I'm right, then you are falsely accusing me and a billion other Catholics and Orthodox of doing something we are not. You are steering people away from the Church by convincing them they worship false gods; depriving them of the Eucharist forever. You'd be bearing false witness.
Just so you know, I'm Catholic and I know who I worship. I will have no problem looking Christ in the eye someday. Will you?
Rebuttal for these comments is simplicity itself.
Simply cite the online Catechism and ask the poster to locate where Catholics are instructed accord divine worship to any save for God.
