Revelation 13:15 15 And it was given to him to give breath to the image of the beast, so that the image of the beast would even speak and cause as many as do not worship the image of the beast to be killed.
The only allowed religion world wide will be that of the beast. AKA One world religion.
You have ignored one whole clause in that verse — “as many as do NOT worship the image...”
Therefore, NOT one religion.
