Families discovered church for the first time last weekend.
More than 130 people packed out St James Church in Quedgeley for the first of a new monthly series of family-friendly services.
Reverend John Ward wants to attract young families back into the church with the services where traditional hymns are ditched in favour of modern songs, craft-making and a buffet lunch.
An average service at the church usually attracts just 80 people providing a family-friendly version ticks all the boxes.
Reverend Ward said: “It was encouraging to see so many new faces in the congregation. Families seemed to welcome the informality of the service.
“I was heartened by the fact that one young boy told me how much he had enjoyed the craft activity and would like to come again.
“Next month the theme will be ‘Candlemas – Christingle flame’ and I hope I shall be able to welcome even more new families into the church.”
The service on Sunday centred around the visit of the three wise men to the stable to welcome baby Jesus and featured lively songs as well as a special story time for children read by Father John and his puppet Cedric the Fox.
Parents and children joined in with making paper crowns to celebrate the Eucharist.
The children then re-enacted the New Testament story and became wise men or kings with a procession around the church, leaving gifts at the nativity scene.
The service will be repeated on the first Sunday of every month and each service will adopt a theme.
