During Translation I found a small error in the leaflet. It's not a large thing, but it might confirm the typical "apostates are liars" opinion.
Your leaflet says:
According to The Finished Mystery ... Jesus "assumed the office of king" in 1878 (p66).
But this is not true. According to the book, the year 1878 is NOT "the date at which our Lord assumed the office of King", but it is corresponding to this date. The full paragraph says:
So then.— "The Spring of 1878, corresponding to the date at which our Lord assumed the office of King, rode on the ass, cleansed the Temple of its moneychangers, and wept over and gave up to desolation that nominal church or kingdom, marks the date from which the nominal church systems are not the mouth-pieces of God, nor in any degree recognized by Him."— B235.
Of course there may be other passages that claim that Jesus would have become King in 1878, but this paragraph does not.
