Evensong was created by Thomas Cranmer from the sevenfold monastic cycle of prayer -
It is roughly the equivalent of Vespers in the Roman Catholic Church and the Lutheran churches, although it was originally formed by combining the Roman Catholic offices of Vespers and Compline. Although many churches now take their services from Common Worship or other modern prayer books, if a church has a choir, Choral Evensong from the Book of Common Prayer often remains in use because of the greater musical provision. Evening Prayer, like Morning Prayer (Mattins) and in contrast to the Eucharist, may be led by a layperson, and is recited by some devout Anglicans daily in private (clergy in many Anglican jurisdictions are required to do so).
AT St John's we hold Traditional Evensong on the first Sunday of each month, using the service from the Book of Common Prayer (1662).
