Troparion — Tone 8
Having been raised on virtue, you loved the monastic life from your youth, / and having valiantly attained your desire, you lived in a cave; / you adorned your life with the radiance of fasting, persevering in prayer as though bodiless. / Like a bright lamp you illumined the Russian lands, Father Theodosius. / Entreat Christ God that our souls may be saved.
Kontakion — Tone 3
“Today the Virgin...” / Today let us honor a star of Russia, / who shone forth from the East, and came to the West. / The entire world has been enriched by wonders and blessings, / and all of us by grace / and by the establishment of the monastic rule by Blessed Theodosius.
