"Evolutionism" isn't a religion, it's a close personal relationship with reality.
And I'll just repeat an earlier post on the subject of "evolutionism"...
You know, sometimes creationists get accused of making a word up when it just isn't so; like "Darwinist" (coined by Alfred Russell Wallace), or "macro/micro-evolution" (coined by entomologist Yuri Philipchenko) or "evolutionist" (which dates back at least to the 1870s, when T.H. Huxley used it in a letter to Nature, volume 1 no less).
But I was quite sure "evolutionism" was genuine "fundie wordsalad" dressing. Ahem...
"Permanence And Evolution: An Inquiry Into The Supposed Mutability Of Animal Types"
by Sidney Edward Bouverie Bouverie-Pusey (1882)[*].
"[W]hile Darwinism proper is improbable, evolutionism in any form is as yet unproved; while, on the other hand, the more we investigate the facts of inheritance, the more we are compelled to regard differences so slight, that they would usually be considered casual variations, as within the limits of our existing knowledge strictly permanent."
Apparently, on further research, "evolutionism" seems to pre-date even Darwin, and historically referred to a "belief in the mutability of organisms". So in rejecting evolutionism, the poster is saying he doesn't think organisms can change in character at all and all the different breeds of dog, cat, cow, horse, sheep, duck, chicken, turkey, rabbit, goldfish, wheat, barley, corn, rye, hops, apples, oranges, grapes and bananas in the world are either individual creations by God or just figments of our imagination.
[* I found earlier examples, but how could I resist using the one written by someone called Sidney Edward Bouverie Bouverie-Pusey? Now that's a name!]
