By 1850 the group had about 300 members and no institutions, although it did have magazines and a hymnbook.

But this proved a firm enough foundation, and by 1852 the movement had 15 ministers and was growing steadily. In 1861 the movement created a publishing company - the Seventh-day Adventist Publishing Association - and in 1863 it constituted itself as a denomination.

The failure of Trump to arrest all their objects of hate after stupid internet messages that they all had to "interpret" to fit their feelings and desires isn't anywhere near as serious as the absence of a Second Coming. They'll be able to "refine" their claims about what the posts meant, they'll transfer their worship to other con artists (Ivanka? I expect they have a thing for blondes, like Donald does), they'll continue to give money and time to whoever has the nerve to fleece them and risk them killing unbelievers.
