“Whoever isolates himself from the church, i.e., from Christianity as a whole, from the history of dogma in its entirety, loses the truth of the Christian faith. That person becomes a branch that is torn from the tree and shrivels, an organ that is separated from the body and therefore doomed to die. Only within the communion of the saints can the length and the breadth, the depth and the height, of the love of Christ be comprehended.”
