"For the title “Lord God the Pope” see a gloss on the Extravagantes of Pope John XXII, title 14, ch. 4, Declaramus . In an Antwerp edition of the Extravagantes, dated 1584, the words “Dominum Deum Nostrum Papam” (“Our Lord God the Pope”) occur in column 153. In a Paris edition, dated 1612, they occur in column 140. In several editions published since 1612 the word “Deum” (“God”) has been omitted. GC 679.3"
"Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God."
Both passages discuss a figure who exalts himself above God. EGW connects the Papacy with the figure described in 2 Thessalonians 2:4, arguing that the Pope's claim to authority is a form of self-exaltation. The provided quote is historical evidence to support her claim.
"And he shall speak great words against the most High, and shall wear out the saints of the most High, and think to change times and laws: and they shall be given into his hand until a time and times and the dividing of time."
The EGW passage directly references the title used for the Pope, which aligns with the Daniel verse about speaking great words against the Most High. The connection is more than thematic; it's a specific example used to illustrate the prophecy.
