The social media giant has rolled out a new prayer request feature, a tool embraced by some religious leaders as a cutting-edge way to engage the faithful online. Others are eyeing it warily as they weigh its usefulness against privacy and security concerns.

In Facebook Groups employing the feature, members can use it to rally prayer power for upcoming job interviews, illnesses and other personal challenges big and small. After they create a post, other users can tap an “I prayed” button, respond with a “like” or other reaction.

Facebook began testing it in the U.S. in December as part of an ongoing effort to support faith communities, according to a statetment by the company spokesperson.
