I don’t think the church will be any more successful in creating a utopian society or world any better that rest of the folks who tried. We are back to “the right person has not tried it yet” BS of Socialism. Any utopia that was close was only for the leader and the rest of the people suffered (authoritarianism/regency), think of the earlier Louis of France, the Sun King or the sultan of Brunei today.
Christ said his Kingdom is not of this world. The true purpose of the church is not to create an earthly utopia but to prepare us for eternity with God! Heaven and Earth are passing away!
