What are these bonds of unity? Above all, charity "binds everything together in perfect harmony."²⁶⁵ Col 3:14. But the unity of the pilgrim Church is also assured by visible bonds of communion: - profession of one faith received from the Apostles; -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 Cf. UR 2; LG 14; CIC, can. 205.
