As artificial intelligence reshapes daily life, a once-academic idea has entered mainstream debate: posthumanism — the view that technology will so transform the human condition that biological limits, and perhaps even traditional ideas of personhood, will be surpassed. For the Church, this isn’t a thought experiment but a pastoral concern. And in a new address, Pope Leo XIV made it clear that the Church intends to engage this cultural shift at its deepest roots.
Speaking on December 5 to members of the Centesimus Annus Pro Pontifice Foundation and the Strategic Alliance of Catholic Research Universities, the Pope framed the accelerating rise of AI with a pointed question: What does it mean to be human in this moment of history?
The Holy Father noted that artificial intelligence is already altering “critical thinking, discernment, learning and interpersonal relationships.” It is becoming a force shaping imagination, behavior, and the meaning of work and creativity. Where posthuman thinkers see the possibility of transcending human limits through technology, Pope Leo suggested that the danger lies in forgetting the very qualities that make humanity unique: moral freedom, the capacity for love, and the ability to enter authentic relationships.
“Human beings are called to be co-workers in the work of creation, not merely passive consumers of content generated by artificial technology,” he said. AI may expand creative horizons, but it cannot replace the interior life that allows a person to choose the good or seek beauty and truth. He warned that uncritical dependence on machine-generated output risks dulling humanity’s “capacity for wonder and contemplation.”
His strongest concern centered on the young. The Pope urged educators, parents, and policymakers to consider how constant immersion in algorithmic environments shapes “the freedom and inner life” of children. Access to vast information, he said, is not the same as the ability to interpret meaning. Without guidance, the next generation may confuse data with wisdom—an opening for some posthumanist assumptions to take firmer hold.
“The new generations must be helped, not hindered, on their path to maturity,” he said. Young people need formation that strengthens their ability to discern, to dream boldly, and to use digital tools “with their own intelligence.” The broader culture may ridicule life’s ultimate questions, but the Pope insisted that those questions are essential precisely now, when technology tempts society to outsource thinking.
Pope Leo also challenged the common belief that AI’s evolution is inevitable and beyond human control. Such fatalism, he argued, erodes public confidence in our ability to guide innovation toward the common good. Instead, he called for coordinated action by governments, industry, universities, finance, civil society, and religious communities to ensure that AI development remains accountable and inclusive.
This cooperation, he said, must rise above political or financial interests, especially in an era when technological power is increasingly concentrated. Only through “widespread participation” can society shape AI in ways that serve rather than diminish humanity.
He concluded by urging continued research rooted in Scripture and the Church’s Magisterium —a reminder that the Church’s vision of the human person is not some nostalgic defense of the past but a guide for navigating a future where the boundaries of humanity are being renegotiated.
