In one part of the world, one particular religious ideology will prevail; in a different part of the world, a different religious ideology will prevail. This is entirely useful to your visitors, for they do not care if there is more than one religion so long as there is order, conformity and allegiance. Having no religion of their own that you could possibly follow or identify with, they will use yours to engender their own values. For they value only total allegiance to their cause and to the collectives and seek your total allegiance to participate with them in ways that they prescribe. They will assure you that this will create peace and redemption in the world and the return of whatever religious image or personage is considered of the greatest value here.
This is not to say that fundamental religion is governed by alien forces, for we understand that fundamental religion has been well established in your world. What we are saying here is that the impulses for this and the mechanisms for this will be supported by the visitors and used for their own purposes. Therefore, great care must be given by all who are true believers in their traditions to discern these influences and to counteract them if possible. Here it is not the average person in the world that the visitors seek to convince; it is the leadership.
