St. Callistus the Patriarch of Constantinople - Troparion & Kontakion

Troparion — Tone 4

You appeared to your flock as a rule of faith, / an image of humility, and a teacher of abstinence. / Because of your lowliness, heaven was opened to you; / because of your poverty, riches were granted to you! / O Holy Patriarch Callistos, pray to Christ our God to save our souls!
