The 'Collection of Hymns' was first published by John Wesley in 1780 and contained over 1000 hymns, written mostly by his brother Charles. The hymnal drew on the many other hymn books John and Charles Wesley had published over the previous decades and became the most influential hymn book in the history and development of Methodism.
The 'Collection' went through many editions, and it was the ancestor and basis of all subsequent official Connexional hymn books, including today's 'Singing the Faith'. This 1797 edition was "Printed for and sold by G. Whitfield, at the New Chapel, City Road,"
