Readers are lay people in the Church of England, from all walks of life, who are called by God, theologically trained and licensed by the Church to preach, teach, lead worship and assist in pastoral, evangelistic and liturgical work.
The office of Reader is the only lay ministry in the Church of England which is voluntary, nationally accredited, Episcopally licensed and governed by canon. There are now over 10,000 Readers, with men and women represented almost equally.
Although nationally authorised, the scope of ministry and roles undertaken by Readers differs across the dioceses. In addition, each diocese currently provides its own programme of initial and continued training, which are moderated nationally to ensure consistency in preparing Readers for their office, supporting them and helping to keep them up to date.
