Blessed Sacrament Catholic Church members believe someone stole the kneeling king, a sheep and shepherd as a prank.
The church has filed a report with the Wichita Police Department, but investigators have no leads in the theft, which reportedly occurred as early as Monday.
Police say the king and shepherd have a reported value of more than $1,000, making the thefts a potential felony.
The church became aware of the missing pieces Tuesday morning.
A church member gave the 30-piece set to the church nearly 25 years ago.
