694. 16:10 Then the fifth angel poured out his bowl upon the throne of the beast. This symbolizes influx into the people's faith.

The angel's pouring out his bowl means, symbolically, here as before, influx, and the throne of the beast means, symbolically, where faith alone reigns. A throne symbolizes a kingdom or realm, and the beast faith alone (nos. 567, 576, 577, 594, 601, 660).

That a throne is also mentioned in connection with the reign of evil and falsity is apparent from the following:

The dragon gave (the beast) its power, its throne, and great authority. (Revelation 13:2)

I know your works, and where you dwell, where Satan's throne is. (Revelation 2:13)

I watched till thrones were cast down, and the Ancient of Days was seated. (Daniel 7:9)

I will overthrow the throne of kingdoms, and... the strength of the kingdoms of the nations. (Haggai 2:22)

(Lucifer said:) "I will exalt my throne above the stars... (Isaiah 14:13)

And elsewhere.

605. To receive from it a mark on their right hand and on their foreheads. This symbolically means that no one is acknowledged as a Protestant Reformed Christian but one who accepts that doctrine in faith and love.

To receive a mark means, symbolically, to be acknowledged as a Protestant Reformed Christian, or to be among those who confess what the doctrine teaches. The mark is an acknowledgement that the person is such a one, and also a confession that he is such. The right hand symbolizes everything in a person relating to the power of his intellect, thus to his faith; for the right hand symbolizes a person's power (no. 457). The forehead symbolizes everything in a person relating to the power of his will, thus to his love; for the forehead symbolizes love (no. 347).
