The articles above are good. Carl Olsen’s book called Will Catholics Be Left Behind is an excellent book that goes into great detail. As for a short answer from a former Baptist who used to teach it, we Catholics do believe it, but we believe it is the second coming of Christ at the end of time. We don’t call it the rapture, but techiqually that is what being caught up to meet Jesus in the clouds means. But those who teach a different rapture usually teach that the rapture happens right before the time of the Antichrist, and the only ones who get raptured are those who are “saved”. They believe that those who are saved will not have to endure the time of the Antichrist.
