Yes, my quote does not prove the mutability of Judeo-Christianity. You can not prove anything with a single quote from the bible. The bible was written by authors of very different opinion and background, and for almost any quote you can find a counter-quote.

Nevertheless I object to the idea that religions don't change but only spawn. Almost all fractions of Christianity, even the most fundamentalist section of our friend Nitro_2008, have remarkably changed since their beginning.

The Hebrew religion of the year 60 AC, the time when Paulus founded Christianity, was very different to the Hebrew religion of Moses' time 1300 years before. The changes are reflected in the Bible. There were many changes in religious laws, in the character of god, and in god's covenant with Israel. At the beginning, it was a physical covenant, with god's duty to protect Israel by killing all its enemies. In the end, the covenant was spiritual only. Although Israel fulfilled their part after their return from the Babylonian exile, god never protected them against the Romans, and allowed full extinction in 130 AC. The character of the covenant and the character of their god had changed to Israel's misfortune.

You can even see the change statistically by just comparing god's kill rate. The bible often mentions the numbers of the people killed by god. The kill rate, from an average of several 10,000 per year at Moses' time, goes constantly down to a few per century. The last person ever killed by god, before his suicide in the Jesus incarnation, was king Herod.

Religions do change. This usually shows in struggles between the progressive and the conservative fractions - that's exactly what you're seeing today with the conservative fundamentalists in the US. In an attempt to maintain the identity of their particular religion, they have developed that strange counter-science that you can find on their websites.
