It bugs me when people refer to a ‘secret rapture.’ The use of the term is outmoded and ambiguous. 
It stands like a scarecrow with a target painted on his chest, inviting straw man attacks. The secret rapture moniker is used by some Premillennialists who reckon that only believers will be aware of the return of Christ. Unbelievers will be left perplexed at where their ‘religious’ neighbor and bus driver suddenly went.
The secret rapture idea posits that Christ returns with a shout of an angel that only believers can hear (and maybe dogs), an appearance in the sky that only believers can see, a physical resurrection of deceased Christians, which only believers can witness, and then a sudden catching up of all believers into the sky, to accompany Jesus back to Heaven while the seven year tribulation ensues. The image in Premill pulp fiction views the “left behind” world as utterly confused as to the ‘mysterious disappearances’ of a goodly slice of earth’s mostly amiable and cheerful population.
