Troparion — Tone 1
You were enlightened by divine grace through prayer and fasting, / illumined by dazzling Light which is not of this world. / Having received the gift of miracles from God, / you heal the sick and drive away demons from the souls of those who have recourse to your holy relics with faith, O venerable Father Ioannikios. / Glory to Him Who has granted you grace. / Glory to Him Who has strengthened you. / Glory to Him Who through you, grants healing to all.
Kontakion — Tone 8
From your youth, O godly-minded one, you loved the angelic life, / forsaking all earthly pleasures, shining as a star from the world, / you shone forth with spiritual truth and Christ, the Sun of Righteousness. / From Him, you received the gift of healing, curing the illnesses of those who run to your holy tomb with love. / Wherefore, we also venerate your holy memory and cry out to you: Hail, Father Ioannikios.
