"O, what a great and awesome sight that is seen today!"

The Transfiguration of Christ (source)

  
O, what a great and awesome sight that is seen today! He Who is from heaven is perceived, and upon the earth shines incomparably greater than the sun, as the noetic [Sun] of Righteousness, upon Mount Tabor.
-from the Matins Canon of the Transfiguration

Through the prayers of our Holy Fathers, Lord Jesus Christ our God, have mercy on us and save us! Amen!
