The church was last used on Sunday, October 5, for regular church services.
The discovery was however made on Tuesday October 7, when members of the Church choir turned up for practice and found the place ransacked with a number of items missing.
Members of the church said they believe the burglars might have gained access through a window.
One member told St. Lucia News Online (SNO) that the church was broken into a few years ago. The Parish priest was utilising the building at that time.
