Pope Leo stated in his homily during the Mass for the beginning of his pontificate how he “would like that our first great desire be for a united Church, a sign of unity and communion, which becomes a leaven for a reconciled world.”

The following day, he told representatives of other churches, ecclesial communities, and religions that “unity has always been a constant concern of mine, as witnessed by the motto I chose for my episcopal ministry: In Illo uno unum, an expression of Saint Augustine of Hippo that reminds us how we too, although we are many, “in the One — that is Christ — we are one.”

But is unity actually possible? Even just among Catholics — with continuing “liturgy wars” and doctrinal debates and leadership clashes — what does ecclesial unity look like?

Join us at the Seminary for the 2025 Cardinals’ Forum … with special guest Brendan Towell … to discuss how our differences can be turned into communion … a fitting topic during this year’s 1700th anniversary of the First Ecumenical Council of Nicea (which formulated the Creed shared by Christians).
