It is necessary and desired to present an Orthodox defense of dogma and its unchanging status in order to demonstrate how Orthodoxy understands this crucial issue. Since the idea of development is often assumed in other circles, it is presented as being natural. This is precisely how Cardinal Newman presents it in his influential essay. It seems easy to assume that, just as ideas and theories develop and change over time, so too does dogma. This would be the case if dogma were simply ideas and theories about God and salvation.
