Pope Leo is making a serious political miscalculation by aligning the Church with left-wing immigration policy at a moment when European voters are moving sharply in the opposite direction. Framing open borders as a moral imperative alienates the socially conservative Catholics who form the Church's backbone, while lending credibility to governments that actively oppose Church teaching on abortion and marriage. A pope who sides with atheist progressives over populist defenders of Western culture is betting the Church's future on a losing hand.
