For the mystery of lawlessness already works. Only there is one who restrains now, until he is taken out of the way.
      3. His rise is mentioned, 2 Thessalonians 2:6; 2 Thessalonians 2:7. Concerning this we are to observe two things:-- (1.) There was something that hindered or withheld, or let, until it was taken away. This is supposed to be the power of the Roman empire, which the apostle did not think fit to mention more plainly at that time; and it is notorious that, while this power continued, it prevented the advances of the bishops of Rome to that height of tyranny to which soon afterwards they arrived. (2.) This mystery of iniquity was gradually to arrive at its height; and so it was in effect that the universal corruption of doctrine and worship in the Romish church came in by degrees, and the usurpation of the bishops of Rome was gradual, not all at once; and thus the mystery of iniquity did the more easily, and almost insensibly, prevail. The apostle justly calls it a mystery of iniquity, because wicked designs and actions were concealed under false shows and pretences, at least they were concealed from the common view and observation. By pretended devotion, superstition and idolatry were advanced; and, by a pretended zeal for God and his glory, bigotry and persecution were promoted. And he tells us that this mystery of iniquity did even then begin, or did already work. While the apostles were yet living, the enemy came, and sowed tares; there were then the deeds of the Nicolaitans, persons who pretended zeal for Christ, but really opposed him. Pride, ambition, and worldly interest of church-pastors and church-rulers, as in Diotrephes and others, were the early working of the mystery of iniquity, which, by degrees, came to that prodigious height which has been visible in the church of Rome.
