What are these bonds of unity? Above all, charity "binds everything
together in perfect harmony."265 But the unity of the pilgrim

-common celebration of divine worship, especially of the sacraments;
- apostolic succession through the sacrament of Holy Orders, maintaining the
fraternal concord of God's family.266
