John Wesley to Joseph Connly (sic) in Leominster, Herefordshire, September 20th, 1746
John Wesley is writing to Joseph Cownl(e)y and other preachers of the Leominster Methodist society, praising their efforts and encouraging their work: "As many of you have Set Your Hands to the Plough, See that You go on & look not back. (..) Meanwhile, fight the Godd Fight of Faith, enduring the Cross and despising the Shame. Beware that none of You return Evil for Evil, or Railing for Railing, but contrariwise, Blessing."
Methodism in the 1740s was still in its infancy, and many people in Britain saw it as threatening the established Church.
