Changing the Commandments

The 4th commandment was changed and the 2nd commandment removed. Commandment 10 was changed into two commandments 9 and 10. That's insane! http://www.the-ten-commandments.org/romancatholic-tencommandments.html

841 The Church's relationship with Muslims. The plan of salvation also includes those who acknowledge the Creator, the first place amongst who are the Muslims; these profess to hold the faith of Abraham, and together with us they adore the one, merciful God, mankind's judge on the last day. (Catechism of the Catholic Church, LG 16: cf. NA 3.)

Is that crazy or what?
