Murphy Institute co-director Msgr. Martin Schlag delivered the Fall 2025 Archbishop Ireland Lecture hosted by the Saint Paul Seminary. In his lecture, titled “From Leo XIII to Leo XIV: Catholic Social Thought in an Era of Anti-Humanism,” Msgr. Schlag offered a fresh perspective on Pope Pius XI’s vision of society’s essential institutions, building on Pope Leo XIII’s legacy and proposing a fourth pillar: the world of work and economic exchange. Drawing especially from Rerum Novarum, the landmark Church document on labor and social justice recently highlighted by the election and name choice of Pope Leo XIV, Msgr. Schlag set the scene historically, showing how Catholic social teaching evolved from earlier legal and political debates to universal principles that continue to guide the Church today.
Msgr. Schlag was also featured in a recent episode of “Practicing Catholic,” a podcast produced by Relevant Radio and the Archdiocese of St. Paul and Minneapolis, to discuss his inspiration for the lecture. A recording of the episode and summary of the interview may be found on The Catholic Spirit website.
