John the Apostle
Revelation 13:14BSB·traditional attribution

Because of the signs it was given to perform on behalf of the first beast, it deceived those who dwell on the earth, telling them to make an image to the beast that had been wounded by the sword and yet had lived.

Matthew Henry Presbyterian @wholebiblehenry

Those who think the first beast signifies Rome pagan by this second beast would understand Rome papal, which promotes idolatry and tyranny, but in a more soft and lamb-like manner: those that understand the first beast of the secular power of the papacy take the second to intend its spiritual and ecclesiastical powers, which act under the disguise of religion and charity to the souls of men. Here observe, I.

Commenting on Revelation 13:11-18

John Gill Reformed Baptist @doctorgill

And he had power to give life unto the image of the beast,.... Or "breath"; he breathed into it, and animated it; he gave this new religion a sanction, he confirmed and established it, and obliged all in his dominions to embrace and acknowledge it; and this he did by his decrees and canons, and those that refused were delivered over to the secular power...

Albert Barnes Presbyterian @notesbybarnes

Verse 14. And deceiveth them that dwell on the earth by the means of those miracles. Nothing could possibly be more descriptive of the Papacy than this. It has been kept up by deception and delusion, and its pretended miracles have been, and are to this day, the means by which this is done.
