The Holy Club was a group of Christians, including John and Charles Wesley and George Whitfield who met to form a 'method' to be good Christians. They had a list of things they should do each day; such as visit those in prison, visit the sick etc. It was very much a matter of 'works' as none of them at this time were born again'.
On entering Lincoln College go through the right-hand exit from the quadrangle; underneath the bust of Wesley. On entering the next quadrangle you will see a plaque on the wall, above which the Holy Club lived.
