The Ten Commandments appear twice in the Old Testament, in
Exodus 20
and
Deuteronomy 5. The Catholics edit the two slightly different versions together in their catechisms:
www.newadvent.org...
Taking God's name in vain is proscribed by
Deuteronomy 5: 11.
Other issues arising:
Numbering of the commandments is not attested in the Bible at either location. There is some consensus that there are 10 of them, however.
Catholics use images in their worship, they do not worship the images. If the image is of a saint, then they don't worship what the image depicts,
either. Protestants are often unreliable sources of information about Catholic practices.
The
Exodus prohibition about idolatry is conjunctive in form. That is, don't make graven images and worship them. Does that mean do neither,
or just don't do both?
And, of course, neither the Roman Catholic nor Eastern Orthodox churches are
sola scriptura. Any Catholic or Orthodox mass, however, re-enacts
what many Protestants call the Lord's Supper, and that is the organizing principle of the entire service. Last I heard, the Lord's Supper is in the
Bible somewhere.
