The suspect is accused of stealing computers and dozens of Visa gift cards from the 7th Day Adventist Community Church in Woodside just after midnight two weeks ago.
Police say the same man also stole electronics and cash from the Sure Foundation Lutheran Church last week.
In both cases, the suspect forced open doors to gain access to the locations.
No one was injured as a result of these incidents.
The suspect is described as an adult male in his 30s with a medium build.
In the first incident, he was wearing a red baseball hat, a red waist-length jacket, blue jeans and sneakers.
Anyone with information in regards to these incidents is asked to call Crime Stoppers at 1-800-577-TIPS (8477).
