The former Boston United and Grimsby Town player spent a number of seasons playing under current City boss Rod Stringer while at Bishop’s Stortford, scoring 13 goals from 100 appearances in all competitions for the Hertfordshire side.
Thirty-one-year-old Church made a return to Chelmsford in May 2016, having previously spent a short spell with the Clarets in 2012, as boss Stringer moved from Stortford to the Clarets in May 2016.
The experienced midfielder immediately became a fan-favourite at the Melbourne Community Stadium as he made himself a permanent fixture at the heart of the City midfield.
In his first season since returning to the Clarets, the City skipper made 43 appearances and scored five goals as City won the BBC Essex Senior Cup, took Vanarama National League side Tranmere Rovers to a replay in the Round of 16 of the Buildbase FA Trophy and reached the Promotion play-off final against Ebbsfleet United.
Church continued his fine form into the 2017/18 season and - bar a short spell on the sidelines due to injury - held onto his role as captain and made forty appearances and scored once as the Clarets reached the play-offs for a second successive season.
