In the storm and stress of the struggle, which in the latter half of 1520 produced the so-called great Reformation works, the Antichrist theory, in its final form, was made to serve as a bulwark against the Papal excommunication and its consequences. Luther drops all qualifications and henceforth his assertions are positive. The wider becomes the breach separating him from Rome, the blacker must he paint his opponents in order to justify himself before the world and to his own satisfaction. Previous to its publication he summed up the contents of his “An den christlichen Adel” as follows: “There the Pope is severely mauled and treated as Antichrist.”[408] As a matter of fact, the comparison is so startling that he could well speak of the booklet as “a trumpet-blast against the world-destroying tyranny of the Roman Antichrist.”[409] In the writing “On the Babylonish Captivity,” a few weeks later, he exclaims: “Now I know and am certain that the Papacy is the empire of Babylon.” “The Popes are Antichrists and desire to be honoured in the stead of Christ.... The Papacy is nothing but the empire of Babylon and of the veritable Antichrist, because with its doctrines and laws it merely makes sin more plentiful; hence the Pope is the ‘man of sin’ and the ‘son of destruction.’”[410] Hereby he had prepared the way for his attack upon Leo the Tenth’s Bull of Excommunication, which he published in German and Latin at the end of October, 1520, under the title, “Widder die Bullen des Endchrists” and “_Adversus execrabilem Antichristi bullam_.”[411] Such a name was well calculated to strike the fancy of the masses, and there cannot be the slightest doubt that Luther welcomed it as a taking, popular cry. It is easy to meet the objection that the Papal Antichrist was nothing more to Luther than a serviceable catchword, and that he never meant it seriously. That such was not the case we have abundantly proved already; on the contrary, we have here a clear outgrowth of his pseudo-mysticism. He ever preserved it as a sacred possession, and it found its way in due season into the Schmalkald Articles[412] and into the Notes Luther appended to his German Bible.[413] The idea, which never left him, of the world’s approaching end—with this we shall deal at greater length in vol. v., xxxi. 2—is without a doubt closely linked with his cherished theory of his being the revealer of Antichrist and the chosen instrument of God for averting His malice in the latter days.
