At a Mass celebrated in the chapel of Domus Sanctae Marthae on April 16 (video), Pope Francis thanked (and prayed for) pharmacists and preached on the readings of the day. The Pope invited those watching the Mass to pray St. Alphonsus Liguori’s act of spiritual communion. The Mass concluded with adoration and Benediction of the Most Blessed Sacrament and the chanting of the Regina Caeli.
