Irmos: Christ is my power, my God and my Lord, the honored Church doth sing, crying out in godly manner with a pure mind, keeping festival in the Lord.
Theotokion: O blessed Mary, thou setting aright of men, we know thee, alone among women, to be the Mother who knew not man, the immaculate Virgin, the undefiled Maiden.
Desiring to confess the one Lord and God of all, Who alone is compassionate, through their sufferings the martyrs have received His kingdom.
Strengthened by the power of the Cross, O martyr Thyrsus who art most rich, like a youth thou didst endure the laceration of thy body, the raging of the fire, and the onslaught of wild beasts and the sea.
Adorned with the wounds of thy struggles as a warrior of Christ, O martyred athlete Leucius, thou didst render thy soul more radiant than the brilliance of the sun.
