[af_vet_1981]

... like the mistranslation of apostasia, used as a wedge between Protestant revolutionaries and the Catholic Church to mean everything from breaking away from mother Church to falling away from the Gospel; but apostasia as used in the day that word made it into the Scriptures meant 'departing'.

Translation of apostasia in bold below (could also add other Septuagint translations from Hebrew where apostasia is used for revolt; it is not used for a rapture):

In the mean while the king's officers, such as compelled the people to revolt, came into the city Modin, to make them sacrifice.

And they are informed of thee, that thou teachest all the Jews which are among the Gentiles to forsake Moses, saying that they ought not to circumcise their children, neither to walk after the customs.

Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition;

apostasía (from 868 /aphístēmi, "leave, depart," which is derived from 575 /apó, "away from" and 2476 /histémi, "stand") – properly, departure (implying desertion); apostasy – literally, "a leaving, from a previous standing." [http://biblehub.com/greek/646.htm]
