What the sources establish

Britannica and parliamentary heritage print the 1521 papal grant of Fidei Defensor after the Assertio septem sacramentorum circulated against Luther.

Britannica and UK Parliament supremacy-heritage pages independently locate the 1521 title.

Not established: unique personal authorship of every sentence, or that 1521 caused 1517.

Henry VIII did not file a later UNESCO form, a later Loeb colophon, or a later museum label as a personal act. Later irony is commentary.
