With the exception of Lutherans (who apparently use the same numbering system for the Decalogue as Catholics) Do other Protestants have a consistent method for numbering the 10 commandments?
Catholics say the first 3 are about God. Then the last 7 about Man. Whereas, I've seen Protestants refer to this as the 4th commandment and then top it off with "thou shalt not covet thy neighbor's stuff, and by stuff we also mean wife".
Also, other than keeping the Dec in the Decalogue, what is the reason behind munging the two separate commandments that are against adultery and expanding on the one commandment against profaning God? Is there something in the Catholic teaching that favored the 3/7 split as a couple of the more beautiful numbers in Creation that was rejected by Protestants?
