Please tell me precisely what is "unChristian" about:
1. placing the interests of the entire world above those of individual nations; and
2. a process by which the people of the world are unified into a single society and function together
We know that when Jesus returns, the world will indeed be unified into a single society - the scriptures are pretty clear about this.
