The Roman Catholic Church even changed the Ten Commandments which God wrote on two stone tablets.
Why did the Roman Catholic Church change the Ten Commandments written in the Bible? They took away the second commandment, “You shall not make for yourself an idol.” God prohibited idolatry through the commandment, “You shall not make for yourself an image in the form of anything in heaven above or on the earth beneath or in the waters below, and you shall not bow down to them or worship them.” However, the Catholic Church set up cross images, and made and worshiped Mary and Saints statues. They have a doctrine that contradicts the commandment, “You shall not make idols.” In the eyes of the Catholic Church, the 2nd commandment was a prickly one. After all, they took away the 2nd commandment.
They also changed the 4th commandment from “Keep the Sabbath day” to “Keep the Lord’s Day.” If the Sabbath were the same day with Sunday which is called the “Lord’s Day,” they would not have changed it to “Keep the Lord’s Day.” The Roman Catholic Church introduced the Sunday service into the church. They had no choice but to change the Ten Commandments in order to stick to the day of sun-worship.
The 10th commandment, “You shall not covet your neighbor’s house,” includes “You shall not covet your neighbor’s house, your neighbor’s wife, or his manservant or maidservant, his ox or donkey, or anything that belongs to your neighbor.” However, the number of the Ten Commandments reduced to 9 because the 2nd commandment was abolished. So the Catholic Church divided by force the 10th commandment into two: “You shall not covet your neighbor’s wife” and “You shall not covet your neighbor’s goods.”
The reason the Catholic Church changed the Ten Commandments is because they violated squarely the Ten Commandments, the Word of God. The right faith is that they correct their behaviors if they are against the words of God. For this, we look at the Word of God. But, the Roman Catholic Church changed the Word of God when they found their acts deviated from the Word of God.
The Bible says that the one who will speak against God will change the laws of God.
He will speak against the Most High and oppress his saints and try to change the set times and the laws [GNT: their religious laws and festivals]. The saints will be handed over to him for a time, times and half a time. (Daniel 7:25)
