Then the lawless one will be revealed, whom the Lord will kill with the breath of his mouth, and bring to nothing by the brightness of his coming;
This verse teaches that when the man of sin is revealed he will be destroyed by the Lord in the final day with the simple breath of His mouth. As powerful as the Pope is, and as tremendous as his organization is, it will fall to ruin with the breath of Jesus Christ in the final day. The great event may be compared to a big ant bed that has taken those hard working little creatures a long time to prepare yet with one footstep one can destroy it all. The great mighty evils of the Roman Catholic church will be destroyed with no problem by the divine being in Heaven.
