Troparion — Tone 4
From your youth you clung to Christ’s love / And you eagerly kept his laws. / You were enriched with miraculous gifts / And now pour forth healings, Theodore, David and Constantine / Pray to Christ our God to save those who honor you!
Kontakion — Tone 8
While in the flesh you were radiant lamps living like the angels. / By fasting, vigils and faith you grew like the trees in paradise. / You blossomed in prayer through the grace you received. / You have become mighty physicians, healing infirmity of souls. / O glorious wonderworkers Theodore, David and Constantine, / Pray to Christ our God for the forgiveness of those who venerate your memory!
