The rapture is clearly a biblical even as referenced in 1 Thessalonians 4:17 . I belive most catholics are Amillennialists where the general non-denominational specific teachings (while highly subjective by congregations) are typically based on postmillennialism. It's not whether Christianity feels it's real or unreal, just figurative or literal and whether a timeline is able to be established.
"There ought to be a term that would designate those who actually follow the teachings of Jesus, since the word 'Christian' has been largely divorced from those teachings, and so polluted by fundamentalists that it has come to connote their polar opposite: intolerance, vindictive hatred, and bigotry." -- Philip Stater, Huffington Post
