What I consider an intriguing possibility is a 'rapture' similiar to what many evangelicals expect to occur today having taken place sometime between AD 67 & AD 70. Their is an awfully odd silence in the writings of the Apostles,etc. re: Christian history/teaching between roughly AD 70 and AD 150 (it took about another 70 or 80 years for those Christians who were not 'watchful' or 'wise' to gather themselves and sally forth again to the pages of history. It would also be in that era that the idea of a delayed parousia arose. That a 'rapture' occurred concurrently with the parousia and the destruction of Jerusalem in AD 70 would explain the dangling ending to Mark, the abrupt end in Acts (what happens next?), the sudden disappearance in the late 60's (67 to 70) of many of the Apostles.
Apart from that, I would interpret the rapture as simply a reference to the gathering of the saints to be with Christ at death. But, it seems more to refer, again, back to the first century and the translation from the Old Covenant to the Spiritual Realities of the New Covenant.
