St. Isaac the Syrian's Prayer for Contrition and the Great Doxology

The post presents a short prayer attributed to St. Isaac the Syrian that asks for a contrite heart and strength so that acceptable tears may flow and the heart may be illumined by pure prayer. Alongside this prayer, a video summary describes the structure of a liturgical hymn that begins by glorifying the one who has shown the light, continues with the angelic hymn from Luke 2:14, glory to God in the highest and on earth peace, good will among men, and concludes with the worshippers praising, blessing, worshipping, glorifying, and giving thanks to God for his great Lord.

The video points list three key lines: glory to the one who has shown the light; glory in the highest to God and on earth peace, good will among men; and we praise you, we bless you, we worship you, we glorify you, we give thanks to you for your great Lord. The post combines a personal petition for compunction from a seventh-century Syrian ascetic with an outline of the Great Doxology, a hymn used in Orthodox matins and other services.
