The Prayer of Manasseh is used as a lesson in the Book of Common Prayer 1662 International edition. It is Canticle 14 in the Episcopalian BCP of 1979. It is canticle 52 in Common Worship. IIRC Luther wrote a book on repentance that was a commentary on the text. I point this out so you can't claim it is just an Eastern Orthodox/Eastern Rite Catholic issue. But Logos couldn't be bothered to find even the most basic information on the text?
How hard is it to find that the traditional author is Manasseh, the theme is repentance, … Please put some effort into completing the data in this tool.
