On a sunny afternoon in May, Zachary Galante was sitting in a conference room in St. Francis de Sales Seminary with several other young men, talking about what it meant for them to choose the Catholic priesthood in the year 2024. The next morning, they would make lifelong promises of celibacy and obedience, and they were palpably elated by the prospect.

“It’s a beautiful life,” Deacon Galante, soon to become Father Galante, said.

There was a time where the church “maybe apologized for being Catholic,” he said later in the conversation. He and the other new priests agreed they were called to something different: advancing the Catholic faith, even the parts that could seem out of place in an increasingly hostile world. “The church is Catholic, and so we should announce that joyfully,” he said.

In an era of deep divisions in the American Catholic Church, and ongoing pain over the continuing revelations of sexual abuse by priests over decades, there is increasing unity among the men joining the priesthood: They are overwhelmingly conservative in their theology, their liturgical tastes and their politics.

Priests ordained since 2010 “are clearly the most conservative cohort of priests we’ve seen in a long time,” said Brad Vermurlen, an assistant professor of sociology at the University of St. Thomas in Houston, who has studied the rightward shift of the American priesthood. Surveys tracking the opinions of priests have found that, starting in the 1980s, each new wave of priests in the United States is noticeably more conservative than the one before it, Dr. Vermurlen said.

His and his colleagues’ analysis found newer priests were significantly more conservative than their elders on questions including whether homosexual behavior is always a sin, and whether women should be able to serve as deacons and priests, for example.
