He will be rejected by the whole world just as he was rejected by everyone around him in the Middle East by the fornicators, adulterers, abortionists, secular humanists......
In His second coming He will manifest Himself in a way that clearly identifies His Church, therefore He will be rejected also by all Protetants, Eastern Schismatics, Jєωs, and the whole world. Only a handful of people of good will will accept Him, just like the first time.
