Derived from the Russian sobiratj, meaning "to gather" or "a state of being united." It is identified with Alexy Khomyakov's concept of the church as a theandric organism of love, effecting its unity as a free association of all peoples in Christ, patterned on the communal unity of the first Christians (Acts 2.42), and corresponding to the Greek term κοινωνία. Between what it considers a kind of mechanical unity based upon exterior authority—this it attributes to the Roman Catholic Church—and the individualistic excess of liberty—this it attributes to Protestantism—the Orthodox Church considers that it realizes a synthesis of such opposites in its characteristic of a free communion of all in charity. Its catholicity, termed sobornaja, equivalent to the Greek καθολικη, is interior; it diverges from the concept of external authority as vested in the person of the pope, whose prerogatives of primacy and infallibility are, according to the Orthodox, immanent to the church as a whole. The covenant principle of sobornost goes beyond the usual idea of conciliarity by seeing the government and sovereign magisterium of the church as residing in the college of bishops, equal in dignity and rights, who only when assembled in a universal synod legislate on matters of faith or regulate affairs of ecclesiastical government affecting the universal church. While C. Lialine associated this idea only with "dialectical solidarity" in the Oecumene, G. Dejaifve considered the concept of sobornost to be more than mere feeling and fellowship; he claimed that when rightly understood it is compatible with the hierarchical principle, even with that of a supreme papal authority.
