I don't know Jeff..... a global religious system seems so far from being a reality. Even if Jésus were to return there would be those that dispute it and would adhere to what they already believe. Man can be such a creature of habit.

Many believe that Jésus has already returned... Read any of the Bahai literature.... even while we speak they have a universal house of justice operating in Israel. http://info.bahai.org/universal-house-of-justice.html
