Praise

CNA Staff, Dec 27, 2025 / 07:00 am (CNA).

Apps that promise to help re-create digital versions of deceased family members using AI pose a “spiritual danger” to Catholics and others who may use the technology in place of healthy grief, experts say.

The AI company 2wai ignited a controversy on social media in November after it revealed its eponymous app, which will allow users to fabricate digital versions of their loved ones using video and audio footage.

App co-founder Calum Worthy said in a viral X post that the tech could permit “loved ones we’ve lost [to] be part of our future.” The accompanying video shows a family continuously interacting with the digital projection of a deceased mother and grandmother even years after she died.

The reveal of the app brought praise from some tech commentators, though there was also considerable negative reaction. Many critics denounced it as “vile,” “demonic,” and “terrifying,” with others predicting that the app would be used to ghoulish ends such as using dead relatives to promote internet advertisements. 

Tech ‘could disrupt the grieving process’

2wai did not respond to requests for comment on the controversy, though company CEO Mason Geyser told the Independent that the ad was deliberately meant to be “controversial” in order to “spark this kind of online debate.” 

Geyser himself said he views the app as a tool to be used with his children to help preserve the memories of earlier generations rather than as a means to having a relationship with an AI avatar. “I see it … as a way to just kind of pass on some of those really good memories that I had with my grandparents,” he said. 

Whether or not such an app is compatible with the Catholic understanding of death — and of more diffuse, esoteric topics like grief — is unclear. Father Michael Baggot, LC, an associate professor of bioethics at the Pontifical Athenaeum Regina Apostolorum, acknowledged that AI avatars “could potentially remind us of certain aspects of our loved ones and help us learn from their examples.”

But such digital replicas “cannot capture the full richness of the embodied human being,” he said, and they risk “distorting the dead’s legacy” by fabricating conversations and interactions beyond the dead’s control. 

Catholic leaders have regularly remarked on both the heavy burden of grief and its redemptive power. Pope Francis in 2020 acknowledged that grief is ”a bitter path,” but it can “serve to open our eyes to life and the sacred and irreplaceable value of each person,” while helping one realize “how short time is.”

In October, meanwhile, Pope Leo XIV told a grieving father that those mourning the death of a loved one must “remain connected to the Lord, going through the greatest pain with the help of his grace.” 

The Resurrection, he said, “knows no discouragement or pain that imprisons us in the extreme difficulty of not finding meaning in our existence.”

Brett Robinson, the associate director of the McGrath Institute for Church Life at the University of Notre Dame, warned that there is “spiritual danger” in technology that outwardly appears to bring loved ones back from the dead. 

Technology is not a neutral product, he said, but one that “has a profound ability to shape our perception of reality, regardless of the content being displayed.”

“In the case of re-presenting dead loved ones we meet one such case where prior conceptions about identity, vitality, and presence are being reshaped along technological lines,” he said.  

“If someone who no longer exists in human form, body and soul, can be ‘resurrected’ from an archive of the digital traces of their life, who or what are we actually engaging with?” he said. 

Robinson argued that present modes of technology have echoes of earlier centuries “when the cosmos was filled with presence — the presence of God, of angels, of demons, and of magic.” 

The problem at hand, he said, is that the “new magic” of modern technology “is divorced from the hierarchical, ordered cosmos of creation and the spiritual realm.”

Donna MacLeod has worked in grief ministry for decades. She first became involved in Catholic grief counseling after the death of her youngest daughter in 1988. The funeral ministry evolved into Seasons of Hope, a grief support program for Catholics that “focuses on the spiritual side of grieving the death of a loved one.”

MacLeod said the program is one of “hospitality and spirituality” that arises in an intensive community of individuals suffering from grief. 

“It builds parish communities,” she said. “People discover they’re not alone. That’s a big deal to grieving people — a lot of people feel very alone in their loss.” 

“And society expects everybody to move on,” she continued. “But grief has its own timetable. Those who are grieving start to understand that the Lord is with them and that he really cares about them. There’s hope and healing at the end of it.” 

“It’s doing what Christ asks us to do — walking with each other in hard times,” she said. 

Regarding the AI avatar technology, MacLeod acknowledged that those who have lost a loved one make it a “very high priority” to “seek connection” with the deceased. 

“People will say, ‘I’m not taking my loved one’s voice off of my answering machine,’” she said. “Or we have people taking out videos of family gatherings so they can see their loved ones again.”

“Everyone seeks to still be connected with their loved ones,” she said. “It’s related to our Catholic faith and the communion of saints — people feel this spiritual connection with their loved ones.”

MacLeod described herself as “on the fence” about how people could be affected by AI avatar apps. There could be “emotional and psychological risks interacting with AI versions of loved ones,” she admitted, though she said that many users “might look at it, but not get hung up on it,” unless they have underlying mental health issues. 

But “where the difficulty arises is that some people get stuck in the denial stage,” she said. Those suffering from grief can get desperate in such circumstances, she said, and sometimes resort to means such as mediums or psychics, which MacLeod pointed out the Church explicitly forbids. 

Whether or not AI avatars fall under that forbidden category is unclear. The Catechism of the Catholic Church expressly outlaws any efforts at “conjuring up the dead.” The use of mediums or clairvoyants “all conceal[s] a desire for power over time, history, and, in the last analysis, other human beings,” the Church says. 

Baggot said apps like 2wai’s “assemble data about the deceased without preserving the person.” 

He further argued that AI avatars “could also disrupt the grieving process by sending ambiguous signals about the survival of the departed person.”

Robinson, meanwhile, acknowledged that it is “good to want to connect to deceased loved ones,” which he pointed out we do “liturgically through prayer and memorials that honor those souls that are dear to us.” 

He warned, however, against “technocratic creators of complex computational machines that are becoming indistinguishable from magic.”

Such technology, he said, alters “the spiritual order” in ways “that are disordered and disembodied from the ritual forms that sustain religion and our belief that our eternal destiny rests with God in heaven and not in a database.”
