 Khomyakov's concept of the "catholicity" of the Church as "universality", in contrast to that of Rome, reflects the perspective from the root-meaning of the word "liturgy" (λειτουργία), meaning "work of the gathered people".As a philosophical term, it was used by Nikolai Lossky and other 20th-century Russian thinkers to refer to a middle way of co-operation between several opposing ideas.It was based on Hegel's "dialectic triad" (thesis, antithesis, synthesis), but in Russian philosophy, it would be considered an oversimplification of Hegel.
