Yep, as is confessed at every service at pretty much any "traditional" denomination. "He shall come again to judge the quick and the dead" from the Apostle's Creed, "He will come again in glory to judge the living and the dead and his kingdom will have no end" from the Nicene Creed, and "Christ has died, Christ has risen, Christ will come again" from the Anglican Book of Common Prayer". No one really questions that our Lord is coming again. It's the unscriptural junk that has become attached to that truth that makes for friction. The ridiculous date setting, the antichrist du jour, pure cloud-cuckooland stuff like the "flying saucers in the End Times" thread that springs back up every three or four months, and every other kind of lunacy that you can imagine shoveled into Last Things.
Sometimes it's a matter of denominational butt covering, like the SDA "Investigative Judgement" the Jehovah's Witnesses doctrine that in 1914 "the appointed times of the nations” ended, and Jesus Christ was installed as God’s heavenly King", both contrived to paper over failed dates for our Lord's return. Sometimes it's a matter of a misreading of Scripture, a lot of the time it's based on a misunderstanding or ignorance of history or science or both, and sometimes it's just unmitigated craziness. But there's a ton of eschatological doctrine out there that very seriously needs to be unbelieved.
So how do we know which is which? Simple, IMO. It has to be centered on our Lord Christ. Not on Israel, not on Satan, not on the United States (!), not on flying saucers, not on Western Civilization, but God With Us Whose return we anticipate and pray for. Any doctrine that draws our view away from Him is at best rubbish, and at worst diabolical.
I love my King and I want to see his face, don't you?
Then make sure you're focused on Him, and not being distracted by doctrinal contrivances designed to pull your attention away from Him and onto something or someone else.
