Synod of Jerusalem 1672
[T]here are necessarily required the votes and signatures of the other holy Patriarchs, and generally the common consent of all the ecclesiastics, and of others eminent for holiness and wisdom, so as not to be gainsaid by any such.
For the Eastern Church doth not give heed to, or rely upon one, or two, or more who represent a party, but not the whole; that she should be directed as they would, be they who they may, though they be the highest theologians, or be eminent for sanctity, so as to able even to raise the dead, much less the ambitious and deceitful, and who secretly weave, as it were, a spider’s web of trumpery bugbears; but in all the aforesaid agree closely together. For being so led she recogniseth as her teacher the Holy Spirit, and make a profession in nowise out of harmony with the divine word, and the Apostolical and Patriarchal traditions. (Chap 3)
