Gavin Casalegno is best known for playing (the hated) Jeremiah Fisher on Prime Video’s hit series The Summer I Turned Pretty, but away from the love triangle that made him famous, Casalegno has been drawing attention for another reason: he’s using his platform to talk about his Christian faith.
On social media, in interviews and even in the middle of press tours, the 25-year-old actor has been surprisingly candid about prayer, purpose and what it means to follow God in the middle of Hollywood.
On TikTok, Casalegno often speaks directly to his millions of followers about faith. In one video, he warns against complacency.
“You can’t just be a lukewarm Christian,” he said. “God wants all of you, not just the Sunday version.”
@team_gavincasalegno @GavinCasalegno shared a new message about being a lukewarm Christian, and in the comments he shared a very memorable quote, “You are at your strongest when you come to your weakest!” 🤯 We just spoke about this topic at my church this past weekend, so it’s so wild to hear Gavin sharing the exact same message. But it’s so relatable because I’ve been cold and lukewarm at times, but never hot. #teamgavincasalegno #teamjeremiah #gavincasalegno #teamjellyfisher #teamjelly #teamjellyfish #tsitp #thesummeriturnedpretty #goldenretriever #jeremiah #jeremiahfisher #jeremiahfisheredit #primevideo #jerebear #jeremiahandbelly #jere #gavin #gavincasalegnofandom #gavincasalegnoedits #explorepage #gavincasalegnofanpage #fyp #fypシ
Fans flooded the comments with responses, many admitting the short clip challenged them more than they expected.
In another post, Casalegno shared his perspective on finding strength.
“You’re at your strongest when you realize your strength doesn’t come from you,” he told viewers, explaining how relying on God has changed the way he approaches work and relationships.
@team_gavincasalegno @GavinCasalegno just shared his inspiring testimony about the power of praying like your prayers are being heard. Gavin, a friend of God you definitely are 🙏🏻 #teamgavincasalegno #teamjeremiah #gavincasalegno #teamjellyfisher #teamjelly #teamjellyfish #tsitp #thesummeriturnedpretty #goldenretriever #jeremiah #jeremiahfisher #jeremiahfisheredit #primevideo #jerebear #jeremiahandbelly #jere #gavin #gavincasalegnofandom #gavincasalegnoedits #explorepage #gavincasalegnofanpage #fyp #church #religion #maybenotgavin
He has also been willing to talk about more vulnerable aspects of faith. In a video titled “A Personal Encounter with God’s Love,” he explained how repentance became a turning point for him.
“I had to repent. I had to admit I couldn’t do it on my own,” he said. “That’s when I felt God’s love the clearest.”
Even in press interviews, Casalegno doesn’t shy away from talking about his faith. He told People that stepping back from social media has become a way to keep his priorities in check.
“Deleting Instagram and all these apps to kind of check out, to be with my family and be with myself, to spend some time with the Lord—that’s really where I thrive,” he said.

At a time when most young stars are crafting brands and chasing algorithms, Casalegno is choosing something very different.
