The anthem is a setting of a passage from the litany compiled by Thomas Cranmer, Archbishop of Canterbury, and later included in the Anglican Book of Common Prayer. It was composed circa 1679–82 at the beginning of Purcell's tenure as Organist and Master of the Choristers for Westminster Abbey.
Composition
"Remember not, Lord, our offences" is an anthem for an a cappella choir consisting of five voice parts: two soprano parts, alto, tenor and bass (SSATB). Purcell originally composed the 44-measure work in the key of A minor. Some arrangements of the anthem include a continuo instrumental accompaniment. Musicologist and historian Franklin B. Zimmerman (born 1923) designated the anthem as "Z.50" in his catalogue of Purcell's works. The duration of performances and recordings of this work is approximately three minutes.
The lyrics of Purcell's anthem are drawn from a passage in the beginning of the Exhortation and Litany compiled in 1544 by Thomas Cranmer (1489–1556), the Archbishop of Canterbury. Cranmer established the liturgical structures for the Church of England after the Reformation and prepared the church's first official authorised vernacular service. He derived the text of the litany from two medieval Sarum rite litanies and a German litany by Martin Luther. Cranmer added the litany to the 1549 edition of the Book of Common Prayer and it has been included in subsequent editions. Purcell set an excerpt from the litany:
Remember not, Lord, our offences, Nor th' offences of our forefathers; Neither take thou vengeance of our sins, But spare us, good Lord. Spare thy people, whom thou has redeem'd With thy most precious blood, And be not angry with us for ever. Spare us, good Lord.

Purcell Manuscripts: The Principal Musical Sources (Cambridge: Cambridge University Press, 2000), 44, 179. Cummings states that Purcell included it in a collection of anthems compiled in 1683. During this time, Purcell had been appointed Organist and Master of the Choristers of Westminster Abbey in 1679 with the resignation of John Blow. He dedicated the next few years entirely to the composition of sacred music. In July 1682, following the death of Edward Lowe, Purcell was appointed organist of the Chapel Royal—an office which he held simultaneously with his position at Westminster Abbey. In his personal life, Purcell had married Frances Peters (or Pieters) who bore him a son that died shortly after birth.
During the 1680s and tenure at Westminster Abbey and the Chapel Royal, Purcell compiled earlier and contemporary sacred music (including several of his own compositions) into one collection for the use of the choirs of both churches. Two extant manuscripts compiled by Purcell are currently held in the collections of the University of Cambridges Fitzwilliam Museum. Both manuscripts include "Remember not, Lord, our offences".Thompson, Robert “Purcell's great autographs” in Price, Curtis (editor) Purcell Studies (Cambridge: University of Cambridge Press, 1995), 6–34, at 31.
