Thanks for that reference. This will likely have NO RELEVANCE to anyone here, except some of the anointed perhaps, but... Since it has come up.
The 70 weeks from the building of the first temple until the Messiah arrives PARALLELS the rebuilding of the new temple and relates to Jehovah's Witnesses. But it indicates they would come out of a PROTESTANT religion.
Basically, the apostasy is related to the Catholic Church. Time, time and half a time 1260 years is the apostasy period. It ends in 1996 at the end of the last 70 weeks which is 490 years beginning in 1506BCE. The JW connection is that the "temple will come into it's right condition" after 2300 evenings and mornings. An evening and a morning is one day, so 2300 eves and morns are actually 1150 days calculated as 1150 years against the 1260 years. Which means? Which means that basically the "temple" organization, the one recognized as holy enough to be chosen for special work of preaching the good news, etc. would come into existence for the last 110 years prior to 1996, that is, around 1886AD. That is the precise year that the first "Studies in the Scriptures" volume came out, the series of which became the foundation of a new group who eventually became known as Jehovah's witnesses.
Now how that relates to protestantism has to do with the rebuilding of the temple from the apostasy related to the rebuilding at the beginning of the 70 weeks (the 1st of Cyrus in 455BCE began the rebuilding of the temple), in the modern age, this is rebuilding of the spiritual temple. 490 years from 1996 is 1506 and that is when MARTIN LUTHER became a monk. Of course, he then began the "prostestant" movement. Thus Martin Luther and his movement is seen as the spiritual rebuilding of the lost house of God with the eventual focus on one organization that would become the sacred "temple" organization 110 years before the end of the Covenant Period.
That having been noted, it should be apparent that the temple organization, if part of the rebuilding started by Martin Luther, would likewise come out of Protestantism.
So even JWs consider themselves the "original" true Christian religion and thus not stemming from Protestantism, we all know they do, and Biblically they are supposed to. By general comparison they are certainly Prostestant since they are not Catholic. Furthermore, all their early literature is so anti-Catholic they can hardly be classified as non-"Protestant". In Volume 7 of Studies in the Scriptures, the 666 Beast is identified as a number of a Catholic Pope and thus the anti-Christ, so.......
Just some "anointed group TRIVIA" for those interested. Biblically, the temple organization is supposed to come out of Protestantism so JWs, per the Bible are Protestant.
