A flyer advertising "Bring Your Bible To School Day" had families within the Folsom Cordova Unified School District asking questions Thursday.
"It's promoting a particular religion. It has a quote from Matthew on it," Rabbi Yossi Grossbaum with Folsom Chabad told FOX40 Thursday, adding that he got a handful of calls from concerned parents.
"The school seems to be advocating a particular religious group," Rabbi Grossbaum said.
Some students were so upset, they stayed home in protest.
However, officials from the Folsom Cordova Unified School district say the day was not a district sponsored event. The flier was distributed via Peach Jar, a third party website used by the district as an online bulletin board.
Spokesperson Dan Thigpen says officials got a request from a parent to post the flier on Peach Jar.
"At the advice of our legal counsel, we allowed the flier to be posted, out of concern from our legal team, that prohibiting distribution of this flyer could be discriminatory," Thigpen told FOX40 Thursday.
Bring Your Bible to School is a national event sponsored by Focus On the Family, a conservative Christian organization out of Colorado Springs, Colo. The group's website states that the day is meant to "empower students to take their Bibles to school as a visual way to celebrate religious freedom"
"I thought about it. And, I thought okay, I would rather have kids bring bibles to school than guns," one parent said.
FOX40 checked the Peach Jar bulletin board Thursday evening and it appeared the flyer had been taken down.
