ABSTRACT
This chapter discusses the Church history that corresponds to the years shortly following the Quinisext Council, in Trullo, of 691-692. This event played a decisive role in shaping the Byzantine conception of Orthodoxy, articulating on the eve of Iconoclasm a specific bond between dogmatic definition, ritual and the customs of Christian society. The chapter recalls that the Armenian Church adhered only to the first three cumenical Councils and to the Formula of Reunion of 433. At the council convoked at patriarchal see of Duin in 553, the Church confirmed its rejection of the definition of faith of the Council of Chalcedon, thus detaching itself from succeeding Byzantine theological elaborations. The chapter confines itself to the documentation that most securely indicates a prolonged sojourn in Constantinople. Stephen of Siwnik's activity at Constantinople during 712-718 falls within the period of political instability in the Empire, with annual Arab incursions, and these circumstances find their reflection in the canons of the Quinisext Council.
