Almighty God, who willest to be glorified in thy saints, and didst raise up thy servant Gregory the Illuminator to be a light in the world, and to preach the Gospel to the people of Armenia: Shine, we pray thee, in our hearts, that we also in our generation may show forth thy praise, who hast called us out of darkness into thy marvelous light; through Jesus Christ our Lord, who liveth and reigneth with thee and the Holy Spirit, one God, now and for ever.
