O God, whose glory it is always to have mercy: Be gracious to all who have gone astray from your ways, and bring them again with penitent hearts and steadfast faith to embrace and hold fast the unchangeable truth of your Word, Jesus Christ your Son; who with you and the Holy Spirit lives and reigns, one God, for ever and ever. Amen.
Also: don’t forget to say the Jesus Creed during Lent.
