The beast has raised and start the war against the saints, in time of emperor Nero (54-68 A.D.). Nero is not the beast, but the time of the beast start then.
The fusion of Catholic church and Rome, raised up the second beast of revelation, the beast with two horn like the Lamb, but which speaks like the Dragon.
The christianic kingdom has born, and that kingdom is also in our time, and the grate signs, and temptation of falsity, of that second beast, are in here in this present world.
You do not have to wait at any Antimessiah, or beast to come anymore, because both beast of the revelation are here.
Do not deceive your selves.
