In joyful gratitude to Our Lady of the Immaculate Conception, patroness of the Institute, for having received the Pontifical Right status from the Holy See, the Institute organized a pilgrimage to Lourdes, France. His Grace, Archbishop Raymond L. Burke, Prefect of the Supreme Tribunal of the Apostolic Signature, offered a Pontifical High Mass in the Upper Basilica on Saturday, April 25, followed by Solemn Te Deum and Benediction of the Blessed Sacrament.

Later that afternoon, Archbishop Burke gave a spiritual conference together with Monsignor Gilles Wach and Monsignor R. Michael Schmitz, for the several hundreds of faithful who came from all over France, the United States, and beyond. Dozens of Institute priests and seminarians, as well as the Institute's Sisters Adorers wearing their blue choir mantle, led the large crowd of faithful in a candlelight procession in honor of Our Blessed Mother. On Sunday, April 26, Monsignor Wach celebrated a Solemn High Mass and offered Benediction of the Blessed Sacrament in the afternoon to conclude this very beautiful Marian pilgrimage.
