Why God does not permit "reform" of his law

Roman Catholicism and Islam are not permitted by God to implement "reforms" to their basic doctrine and laws of God. This is because they safeguard the standards of theology that humans are to believe and follow in order to hope to achieve the Kingdom of God.

Here is an analogy you will understand. When humans became "modern," they started establishing universally agreed standards of measurement. Every country now has a Bureau of Standards. There is worldwide understanding of how long a meter is, for example, or how many grams in a kilogram, and so forth. There are physical original specimens of each measurement so that countries can ensure that they all conform. Everyone agrees how long a centimeter is, and how many go into a meter.

Likewise the One God has given clear instructions for the conduct of humans and how they should worship and obey God.

Imagine the world if any country decided according to political party or whim of special interest to change how long a centimeter is for their country. Or if they changed it day to day, letting each special interest group have the honor of deciding how long a centimeter is for the day. Liberals who think people do not get enough goods for their money could make the centimeter in their country longer than anyone else's for that day. Women might think they should pick an outrageous length for the centimeter, just so they can show they "can't be pushed around." In no time at all the world would be in chaos if everyone disagreed on basic measurements. Transportation would halt and commerce would fall back to primitive levels (a "handful" or "the length between one's wrist and one's elbow," or "the length of a person's stride"). Would you want your physician to give you a good "squirt" of life saving medicine?

Likewise God will not permit the Churches and Mosques that hold the fundamental truth of human's relationship with God to "reform" to be "progressive" with the times, as that is not progression but deviation from the precious truth. Even if they are the last places on earth to contain the standard measure of truth, like Noah's Ark they will be necessary if humans continue in their degeneration and forget what proper behavior and accurate worship canon and liturgy should be. Just because people do not feel like believing the truth does not mean the standard measures that are God given should or ever will be "reformed."
