Traveling to Spain in June and France in September, Pope Leo XIV will find traditionally Catholic but now staunchly secular countries with an abundance of historic churches but few people in the pews. But there are also signs of a revival of interest in faith among young people. Engaged in lay movements, drawn in by music and social justice causes, these young people say Catholicism gives them a sense of meaning. After generations of steep drops in religiosity and church attendance, they’re approaching the faith with new eyes — and less baggage, which some church leaders say gives them a new opportunity to grow.
