Charles Ellicott Commentary Revelation 18:24

"And in her was found the blood of prophets and of saints, and of all that have been slain upon the earth." — Revelation 18:24 (ASV)

And in her was found . . .—It is not by seductiveness only that her guilt is measured: her hands are defiled with blood: the blood of prophets, who had witnessed against her; of saints, whose holy lives were a protest against her sins and so hateful to her; and of all who have been slain on the earth (Compare to Revelation 17:6, and Note there).

It is not meant that literally all the blood shed by violence had been shed by Rome, or any other single city of which Babylon is a type. Rather, what is meant is that Babylon, the world city, is founded on those principles whose logical outcome is violence, bloodshed, and hostility to the highest right. Those who die by her hands, few or many, are the evidence that the whole tendency of her power is against holiness and truth. In the earthly view, we are guilty of the acts we do; in the heavenly view, we are guilty of all that the spirit and sin of our conduct tends to do.

The spirit of transgression is seen in one act as well as in many; and as it is the attitude of the spirit that God considers, so in a single act the transgression of the whole law may be encompassed. (Compare to Revelation 17:6, and Note there). It is the fatal failure to perceive this that leads people to make light of sin and to undervalue the Cross of Christ.
