The Unity and Uniqueness of the Church
The attributes of the Church are innumerable because her attributes are actually the attributes of the Lord Christ, the Godman, and, through Him, those of the Triune Godhead. However, the holy and divinely wise fathers of the Second Ecumenical Council, guided and instructed by the Holy Spirit, reduced them in the ninth article of the Symbol of Faith to four—I believe in one, holy, catholic, and apostolic Church. These attributes of the Church—unity, holiness, catholicity (sobornost), and apostolicity—are derived from the very nature of the Church and of her purpose. They clearly and accurately define the character of the Orthodox Church of Christ whereby, as a theanthropic institution and community, she is distinguishable from any institution or community of the human sort.
Just as the Person of Christ the God-man is one and unique, so is the Church founded by Him, in Him, and upon Him. The unity of the Church follows necessarily from the unity of the Person of the Lord Christ, the God-man. Being an organically integral and theanthropic organism unique in all the worlds, the Church, according to all the laws of Heaven and earth, is indivisible. Any division would signify her death. Immersed in the God-man, she is first and foremost a theanthropic organism, and only then a theanthropic organization. In her, everything is theanthropic: nature, faith, love, baptism, the Eucharist, all the holy mysteries and all the holy virtues, her teaching, her entire life, her immortality, her eternity, and her structure. Yes, yes, yes; in her, everything is theanthropically integral and indivisible Christification, sanctification, deification, Trinitarianism, salvation. In her everything is fused organically and by grace into a single theanthropic body, under a single Head—the God-man, the Lord Christ. All her members, though as persons always whole and inviolate, yet united by the same grace of the Holy Spirit through the holy mysteries and the holy virtues into an organic unity, comprise one body and confess the one faith, which unites them to each other and to the Lord Christ.
