This happens occasionally… most militant creationists are Protestants, and thus hold to a faith-alone conception of salvation. However, since they believe so strongly that God created the Earth in 6 days and that Earth is 6000 years old, they tend to emphasize the necessity of creationism in practically every public appearance they make, at the expense of… well, at the expense of everything else that Christians believe in. I’ve actually heard someone say once that it’s impossible to believe in Christ’s salvation if you don’t take Genesis literally. Seriously, guys, what the hell (pun intended).
Most Christians raised in a Western tradition (i.e. Catholic or Protestant) know next-to-nothing about Orthodox Christianity (which is mostly centered in Eastern Europe and Russia). Their history is rich and full of wonderful tradition though- it’s surprising how many ideas that Western Christians take for granted are not found in Orthodoxy at all!
Just for clarification: the Rapture (the idea that believers will be whisked up into heaven before the trials of the last days) was developed in the 19th century by a British evangelist. Today, some fundamentalists and conservative evangelicals loudly proclaim its coming, but it’s a minority opinion that’s only really found in America.
