Over the past few days, a new subgenre on TikTok has exploded in popularity: RaptureTok.

It’s become almost impossible to scroll through the social media platform without encountering content about the Rapture—a belief held in some Christian denominations (particularly American Evangelicalism) that believers will ascend to Heaven upon Jesus Christ’s second coming to the Earth.

While it’s unclear exactly how this content took hold, its starting point appears to be a prediction from South African pastor Joshua Mhlakela, who said in an interview with the YouTube channel Cettwinz TV on September 9 that he saw Jesus returning in a vision on September 23 or 24. As of this writing, the video has nearly 400,000 views.

A quick search on TikTok reveals dozens of videos of Christian content creators earnestly preparing for the Rapture, while still more are responses satirizing the trend. This isn’t the first time that a date has been set for the event in question: past hypotheses have included September 1988; September 6, 1994; and May 21, 2011.

Here are a few examples of the #RaptureTok content that’s been dominating feeds.

‘Rapture Trip Tips’

Some of the most referenced RaptureTok videos were made by creator @sonj779, who created a five-part series of “Rapture Trip Tips.” These include pointers like instructing followers on how to subtly hint to friends that they may be Raptured, as well as one video with more than 500,000 views on what to do when you actually begin to ascend toward Heaven.

Popular streamer Hasan Piker responded directly to @sonj779 in a stream questioning the logistics of the Rapture, which has since been clipped by fan accounts and viewed more than a million times on TikTok. While viewers initially speculated that @sonj779’s videos were made in earnest, she’s since confirmed via her comment section that they were intended as satire.

TikTok users are preparing for some to be left behind

Some creators, however, do appear to be preparing for the Rapture in earnest.

Creator Melissa Johnston has posted a series of videos, each with thousands of views, detailing how she’s prepping for the coming days. The videos primarily detail what she’s doing for those left behind after the Rapture, including preparing laminated notecards detailing her beliefs, writing a letter to any remaining loved ones, and purchasing dozens of Bibles from the dollar store.

Commenters are overwhelmingly expressing concern in Johnston’s comments, with one response video positing that she may be experiencing “religious psychosis.”

Former Evangelicals respond

For some creators who no longer identify with their earlier religious beliefs, RaptureTok has struck a nerve. In a video with nearly 200,000 views titled “Rapture Terror,” creator @veronicaandthebabyboo explains that, as a former Pentecostal pastor’s daughter, she’s nervous about the Rapture despite no longer believing in it.

“My entire childhood is just Rapture trauma,” she says. “It’s the reason I can’t plan ahead, it’s the reason I can’t save money—because the Rapture could come.”

She goes on to explain that, as a child, natural phenomena like sun rays and moon beams could be enough to make her question whether the Rapture was imminent. The video has sparked more than 3,000 comments, with viewers sharing their own experiences with childhood “Rapture terror.”

“Granny had a sticker on her dashboard: ‘Warning: Driver of This Car May Disappear at any Moment.’ I got yelled at because I didn’t want to get in the car with her. I. Was. Four,” one user wrote. “I remember calling random people in my church to see if the rapture happened bc my family was late coming home,” another shared. “It runs deep.”
