600. 13:14 And to lead astray those who dwell on the earth, because of the signs which it was granted to do in the presence of the beast. This symbolically means that through their testifications and assertions the clergy lead people in the church into errors.

To lead astray means, symbolically, to lead into errors. Those who dwell on the earth symbolize people in the Protestant Reformed Church, as in nos. 578, 588, 597 above. The signs which the second beast was granted to do in the presence of the first beast symbolize testifications and assertions (nos. 598, 599). The beast from the sea, before whom the signs were done, symbolizes the faith of the dragon among the laity (no. 567); and the beast coming up out of the earth that did the signs, which is elsewhere called a false prophet, symbolizes the faith of the dragon among the clergy (no. 594).

The Lord says something akin to this in Matthew 24:24-26.

A company might have executives setting policy and strategy, engineers designing products, managers handling personnel and others handling various functions. They all do different things -- but if they're doing them with a shared underlying purpose, the company -- and the individuals in it -- will likely be successful. The Lord wants all human society to function in a similar way. We have different skills and individual loves, but if we all share a mutual love -- a love of serving others -- then society will function as one, will be a reflection of heaven and will be a good receptacle for the Lord's love. This can also happen within each of us, as we unify our talents and ideas around a central love. And in an abstract sense, it illustrates how a wide collection of varying ideas can be unified around a shared good intention. That is the kind of love pictured when “one” is used in the Bible, either as a specific number or in the sense of several people or objects “being one.” In more casual references -- when used to identify a specific person or object -- the meaning is relatively literal, and is connected to that person or object.
