A total of 22 groups will hold displays and talk to visitors about what they do. There will be trips up the church tower for £1, free tea and coffee with biscuits all day and a display of the ecclesiastical silver.
The day will run from 10am-4pm.
An evening concert at 7.30pm will feature local duo Take Note – soprano Joanna Hingley and mezzo soprano Margaret Wainwright, who are currently involved in hit ITV1 reality television show X Factor.
They will be accompanied by Margaret's husband Ken, a bass singer and classical guitar player and Eleanor Wilson on piano.
Tickets for the concert are £5 on the door or from churchwarden Mike Day on 07885 819346.
The displays will remain for Harvest Festival celebrations on Sunday October 12. As part of this, choral evensong at 6.30pm will be led by the new director of music Jeremy Jepson of West Deeping, a former chorister at St George's Chapel, Windsor.
