Servant of the servants of God

"Servant of the servants of God" is one of the titles of the Pope and is used at the beginning of papal bulls.

History

, the first Pope to use this title extensively to refer to himself, deployed it as a lesson in humility for the archbishop of Constantinople John the Faster, who had been granted the traditional title "Ecumenical Patriarch"
by a Council convened in Constantinople in 587.
Gregory reportedly reacted negatively to the Patriarch's title, claiming that "whoever calls himself universal bishop , or desires this title, is, by his pride, the precursor to the Antichrist."
