Rt Revd Paul Williams scanned shopping and helped customers pack their bags in the Tesco store.
He visited the supermarket as part of a five-day prayer tour leading up to his inauguration at Southwell Minster over the weekend.
He is meeting people involved in all parts of the church as well as people at their jobs to better understand how everyone plays their part in the community.
Bishop Paul said: "I'm thrilled to be meeting people across the county and learning how the Church can continue to make a big difference in every community, as we live as people of hope in Jesus Christ.
"The prayer tour is a wonderful way to prepare for the inauguration of my ministry at Southwell Minster, as well as celebrating all that God is already doing across the diocese through his Church."
Sue Isbell, a steward at The Church on Rise Park, who also works at the store in the customer services department, invited the bishop to show him what happened behind the scenes at her workplace.
By the end of the week Bishop Paul will have visited a range of local places in South Yorkshire and Nottingham.
He has been learning about the work the church does across the county before he begins his public ministry.
He has also been praying for the people he meets and for their contribution to the mission of the Church.
