The Holy Father appoints bishops from around the world to join various dicasteries (offices) of the Holy See as members. This is one way that the Catholic Church strengthens collegiality—a spirit of communion and collaboration—among bishops and thus unites the whole Church throughout the world. Depending on the dicastery, priests, deacons, or laity may also be appointed as members.
PCID currently has about forty bishop members from six continents. Through being members of PCID, bishops can express their ideas, initiatives, and concerns to the Holy Father and those who carry out the mission of interreligious dialogue led by him.
