The Bible itself does not show with precision, the numbering of the Commandments. It does not do so at all. The set is referred to as "ten" (Ex 34:28, Deut 4:13, 10:4), but the exact numbering is not given in the two slightly different versions of it recorded in the Bible (Ex 20:2-17 and Deut 5:6-21; see also an expanded elaboration of the principles in Ex 34:11-2
. This is as true of the King James Version as of any other. Therefore, no one has the license to be dogmatic about the exact numbering and division, based on the Bible alone -- let alone to make a charge of dishonesty and "removal."
By nature, an abbreviation must leave out certain material, and since the Church has most typically used the Augustinian division of the Decalogue (The Lutherans use the Augustinian division as well), the section of the Decalogue which says:
"You shall have no other gods before me. You shall not make for yourself a graven image, or any likeness of anything that is in heaven above, or that is in the earth beneath, or that is in the water under the earth; you shall not bow down to them or serve them; for I the LORD your God am a jealous God, visiting the iniquity of the fathers upon the children to the third and the fourth generation of those who hate me, but showing steadfast love to thousands of those who love me and keep my commandments.
This gets abbreviated to:
"You shall have no other gods before me.
Some declare that the Catholic Church has "hidden" or "removed" from the Ten Commandments the prohibition of idolatry. They have misinterpreted the idolatry command as a prohibition of all religious images There is nothing wrong with the abbreviation because:
1. Luther himself abbreviated the no false gods/no idols commandment this way.
2. Jews -- who today are even more opposed to religious representations (so-called ‘graven’ statues and pictures) than Protestants -- abbreviate this command in this way.
3. Protestants themselves, even those who separate the two parts of the command, abbreviate them for catechetical purposes, showing that catechetical abbreviation is perfectly fine in principle and is in no way an attempt to "hide" or "remove" any of the Ten Commandments.
4. Teaching the faith to others, especially children, requires an abbreviation of the Ten Commandments for easy memorization since they are otherwise a very long block of material to memorize, longer than any of the commonly recited creeds. It would take a great deal of effort to memorize the Ten Commandments in unabbreviated form. And while God certainly wants each Christian to know the Ten Commandments, he certainly does not expect every Christian (including the billions of illiterate ones in world history) to memorize them in unabbreviated form. That is not an essential Christian duty, and thus Luther, the Jews, and Protestants in general have used abbreviations to aid in memorization.
5. Another reason -- besides their sheer length -- for abbreviating the Ten Commandments is that they contain a lot of historical material that is simply not directly applicable to modern Gentile Christians. Thus God tells the ancient, Jewish audience that he is the Lord, "who brought you out of the land of Egypt, out of the house of bondage" (Ex. 20:2), that they must honor (lit., "glorify") their parents so "that your days may be long in the land which the LORD your God gives you" (Ex. 20:12), and that "You shall remember that you were a servant in the land of Egypt, and the LORD your God brought you out thence with a mighty hand and an outstretched arm; therefore the LORD your God commanded you to keep the sabbath day" (Deut. 5:15). Besides these, there are also numerous cultural-historical references which no longer apply to the overwhelming majority of Christians today -- such as having male and female slaves, cities with gates and walls, oxen, asses, and fields -- while they did apply to what might be called "the Hebrew middle class" in ancient Palestine.
6. Finally, the fact the Church is not trying to "hide" or "remove" any of Ten Commandments by abbreviating them in the memorization formula is indicated by the fact that everywhere else the Church uses them in unabbreviated form. They are there, in all their unabbreviated glory, in every Catholic Bible, including the Vulgate, which was used for a thousand years before the Protestant Reformation, as well as in all the vernacular translations of Scripture before and since the appearance of Protestantism. They are read out unabbreviated during the Scripture readings at Mass (and always have been). And, finally, when catechetics is done and people are taught the Ten Commandments, they are always read and shown the unabbreviated form before being asked to learn the memorization formula.
