The reasons for rejecting the claims of Sardica will be found in connection with the canons set forth by that council. The same is the case with regard to the claims of the Synod in Trullo. It is true that IV. Constantinople, holden in a.d. 869, was for a short while held as Ecumenical by both East and West, and continues to be held as such by the Latin Church down to this day, but it was soon rejected by the East and another synod of Constantinople (879), which undid much of its work, has for the Greeks taken its place. However the Easterns do not claim for this synod an ecumenical character, but confine the number to seven.
