Claim. The period of Christ’s Second Advent began soon after the end of the First World War, derivable from the Principle of Restoration through Indemnity applied to the two-thousand-year New Testament Age and confirmed by the post-WWI rise of Stalin as the satanic antitype of Christ at the Second Advent.
Elaboration. Per dp-1-when-will-christ-return: from the standpoint of providential history, Jesus came at the close of the two-thousand-year Old Testament Age (the Age of the Providence of Restoration); Christ must return at the close of the two-thousand-year New Testament Age (the Age of the Prolongation of the Providence of Restoration), which has been restoring the previous age through substantial parallel conditions of indemnity. The Last Days are now — Christ’s return is today.
The post-WWI confirmation: “soon after the defeat of Germany and the Kaiser (the antitype of Adam on Satan’s side), Stalin (the antitype of Christ at the Second Advent on Satan’s side) rose to power and built up the communist world. This meant that the time was drawing nigh when Christ would return and restore through indemnity the ideal world characterized by interdependence, mutual prosperity and universally shared values.” Therefore “the period of the Second Advent began soon after the end of the First World War.”
This atomic closes the eschatological-timing argument that Chs 4–6 built up: Ch 4 derived the providential-period lengths (1600 / 400 / 2000 years); Ch 5A established the Malachi-to-Jesus and Reformation-to-SA 400-year-preparation parallel; Ch 6B identified WWI as the formation-stage indemnity that enabled the SA. Ch 7 §1 cashes the timing inference into the concrete window: the period of the Second Advent has already begun with the close of WWI (1918).
DP does not name a specific birth-date or a specific person in the §1 text. The window is computational: post-WWI, formation-stage completed, satanic-side antitype identifiable (Stalin). The named identification of Christ at the Second Advent is deferred to subsequent material.
