To him give all the prophets witness - See Isaiah 9:6; Isaiah 52:7; Isaiah 53:5, Isaiah 53:6; Isaiah 59:20; Jeremiah 31:34; Daniel 9:24; Micah 7:18, etc.; and Zechariah 13:1. As Jesus Christ was the sum and substance of the law and the Mosaic dispensation, so all the prophets bore testimony, either directly or indirectly, to him; and, indeed, without him and the salvation he has promised, there is scarcely any meaning in the Mosaic economy, nor in most of the allusions of the prophets.

Remission of sins - The phrase, αφεσις ἁμαρτιων, means simply the taking away of sins; and this does not refer to the guilt of sin merely, but also to its power, nature, and consequences. All that is implied in pardon of sin, destruction of its tyranny, and purification from its pollution, is here intended; and it is wrong to restrict such operations of mercy to pardon alone.

Whether Paul, when in Rapture, Saw the Essence of God?
Objection 1: It would seem that Paul, when in rapture, did not see the essence of God. For just as we read of Paul that he was rapt to the third heaven, so we read of Peter (Acts 10:10) that "there came upon him an ecstasy of mind." Now Peter, in his ecstasy, saw not God's essence but an imaginary vision. Therefore it would seem that neither did Paul see the essence of God. Objection 2: Further, the vision of God is beatific. But Paul, in his rapture, was not beatified; else he would never have returned …

Whether the World is to be Cleansed?
Objection 1: It would seem that there is not to be any cleansing of the world. For only that which is unclean needs cleansing. Now God's creatures are not unclean, wherefore it is written (Acts 10:15): "That which God hath cleansed, do not thou call common," i.e. unclean. Therefore the creatures of the world shall not be cleansed. Objection 2: Further, according to Divine justice cleansing is directed to the removal of the uncleanness of sin, as instanced in the cleansing after death. But there can …
