By Courtney Mares, CNA - Cardinal Giovanni Battista Re, the 91-year-old dean of the College of Cardinals, presided over the liturgy, underlining the need for unity in the Church. “Among the tasks of every successor of Peter is that of fostering communion: communion of all Christians with Christ; communion of the bishops with the pope; communion of the bishops among themselves,” he said... “The unity of the Church is willed by Christ; a unity that does not mean uniformity, but a firm and profound communion in diversity, provided that full fidelity to the Gospel is maintained,” he added.
