Sofa King, you did not get too far in. You got only the bits designed to induce folks to get comfortable. JW’s are nowhere near the Baptists, theologically. Markxxx gets it closer.
In other times, Christians would have referred to Mormonism, CS and JW as “Heresies,” but so many heresies have since become accepted churches it’s no longer styled. Although it’s become usual to call anything not Catholic or Orthodox as “protestant”, still JWs are way out of the theological core of fundamentalism, pentecontalism, or mainstream evangelical protestantism. The average theologically-literate Evangelical Protestant would react to being lumped together with JWs in a way similar to how a Reform Jew would react to being lumped together with Christians.
The key elements in JW doctrine that diverge from mainstream Christianity are:
(a) they deny the Trinity and, of course, the deity of Jesus; the man, Jesus, is said by them to have been “an Angel” (Michael, apparently)
(b) they do not believe in the persistence of the immortal soul; according to JW doctrine it just plain and simply goes away until God miraculously re-instates it on Judgement Day (maybe He stores it in a compressed pkZip archive on removable media)
© their “Hell” after Judgement, for the wicked, is simply to be killed again, this time for good: incinerated into just plain nonexistence
(d) Only 144K outstanding “martyrs” will “go to heaven” with Jesus; as for the rest…
(e) The rest of “the righteous” will live forever physically (i.e. breathing, eating, going to the toilet)on this Planet Earth/Terra/Sol-III, which will be miraculously restored to pristine condition and under the government of Jesus and the 144K saints will be so well managed it will be able to feed and house all forever.
