It seems that everyone I know who claims to be in the right religion, has the idea that their religion is some how more pure or perfect then all others. Whether is a Christian faith as a whole, or an individual sect of Christianity. They are holding a lot of faith in thinking that what they are in, somehow worked itself throughout our ever changing history to become a product today that is nearly exact to what it was like when it began in ancient times. Yet in history, so many things we accept as normal today, have changed drastically from their origin to today. For a couple of example, look at our language. Whether you speak English, French, German or any other language out there. These are passed on phrases and words that have changed so much, that if you spoke English to someone in the year 1000 who claimed to be speaking English, as well, you would have as difficult of a time at understanding them, as you would today with someone speaking Italian to your English. Our way of writing has also changed, with rules of language changing and certain phrases and words evolving and growing. So with these two examples in mind, why would we not think that religion would have also changed from it's origin. Christianity, is not very hard to study and learn that it is not a religion of religious development through some divine inspiration, but more of a political product of agreements and disagreements that lead to control of the masses.
Today, Websters dictionary still edits itself each year to add words, and change definitions as our language develops. We are continuing to see our communication grow and develop, to the point that we can even get confused in our own lifetime with how someone may speak our language in one time to another (just ask your grandparents). Yet, no one seems to be willing to see that their religion, has, does and will do the same. Religion can not be pure, anymore more so then anything that has passed itself down through history, can be. We are a species of continued development and growth. We add, delete and develop new ways of doing everything. Including how we worship a higher power. So if anyone, including our former church, says they are in a pure religion. They are not aware of what an oxymoron that phrase really is.
