“O Divine Lord of all that exists, You have illumined the Apostle and Evangelist Luke with Your Most Holy Spirit, thereby enabling him to represent the most Holy Mother, the one who held You in her arms and said: ‘the Grace of Him Who has been born of me is spread throughout the world.’
Enlighten and direct our souls, our hearts and our spirits. Guide the hands of your unworthy servant, so that we may worthily and perfectly portray your icon, that of Your Holy Mother and of all the saints, for the glory and adornment of Your Holy Church. Forgive our sins and the sins of those who will venerate these icons, and who, standing devoutly before them, give homage those they represent. Protect them from all evil and instruct them with good counsel. This we ask through the prayers of the Most Holy Theotokos, the Apostle Luke, and all the saints, now and ever and unto ages of ages.”
