UNITY: IT'S NOT A PIPE DREAM
When the early Church saw fit to enunciate "One" as one of the Church's distinguishing characteristics, who could've imagined how difficult it would've been to preserve that fundamental feature? That Jesus prayed for His Church to be "one as we [He and the Father] are one" (Jn 17:23) in the hours before His arrest only heightens our sense of His deity: He knew well what would most plague the Church He was about to "obtain with His own blood" (Acts 20:28). Of what does our unity consist? Of what should it consist? Have a look here at the perspective of an Eastern Orthodox Christian regarding what our unity must be based upon.
