Artificial Intelligence and the Catholic Church

What is AI?

Artificial Intelligence (AI) refers to the ability of computers to mimic human-like cognitive functions. Through the use of logic, computers can simulate the reasoning humans use to learn new information and make decisions. This technology is currently utilised in autonomous robots, search engines, targeted advertising, facial recognition, email spam filters, smart assistants (e.g. Siri and Alexa) and self-driving cars. It has the potential to become one of the defining technologies of the century, paving the way for new scientific discoveries and medical advances. However, there has been a growing awareness of the ethical concerns and risks associated with this technology. In 2019, the Alan Turing Institute produced a guide that identified several possible harms that AI systems may cause (see pages 4-5). These include:

  • Bias and Discrimination
  • Denial of Individual Autonomy, Recourse, and Rights
  • Non-transparent, Unexplainable, or Unjustifiable Outcomes
  • Invasions of Privacy
  • Isolation and Disintegration of Social Connection
  • Unreliable, Unsafe, or Poor-Quality Outcomes

Aside from AI’s ‘everyday’ uses, there is also an ongoing international debate surrounding its future utilisation in warfare. For example, the production of Lethal Autonomous Weapons Systems (LAWS) raises significant moral concerns. Several countries, including the UK, USA, and Russia, have resisted calls to draw a legal and moral line around these weapons in the form of an international agreement.


What has the Church said about AI?

On 28 February 2020, the Rome Call for AI Ethics was signed by the Pontifical Academy for Life, Microsoft, IBM, FAO and the Italian Ministry of Innovation. The signatories are committed to ensuring the development of an AI that serves every person and humanity as a whole, that respects the dignity of the human person, and that does not have as its sole goal greater profit or the gradual replacement of people in the workplace. The agreement has Six Principles:

  1. Transparency – AI systems must be explainable.
  2. Inclusion – The needs of all human beings must be taken into consideration.
  3. Responsibility – Designers and developers of AI solutions must act responsibly and transparently.
  4. Impartiality – Systems should not be created or operated according to bias, to protect human equality and dignity.
  5. Reliability – AI must be able to operate reliably.
  6. Security and Privacy – AI systems must work securely and respect the privacy of users

On the same day of the agreement’s launch, Pope Francis welcomed the Call as an “important step”. The Holy Father’s speech can be accessed here.


In October 2021, The Pontifical Council for Culture and the German Embassy to the Holy See hosted a symposium looking at “The Challenge of Artificial Intelligence for Human Society and the Idea of the Human Person”. One of the speakers, Fr James Keenan, wrote an interesting commentary about the event and outlined 7 lessons learned – namely:

  1. The advances of AI are staggeringly more rapid than anyone ever anticipated.
  2. The discourse on AI is occurring within very different language games.
  3. The human being stands as both a contradiction and as a mirror to AI.
  4. The importance of putting humans at the centre of AI development and use.
  5. Not all ‘norm-makers’ are equal.
  6. The present trajectory of AI is a cause of hope and fear.
  7. The human inclination to line-drawing is reassuring, but humanity is not only drawn to concepts.


On 12 November 2021, Cardinal Parolin addressed the 41st Session of the UNESCO General Conference. He said: “For the Holy See, the principle that not everything that is technically possible or viable is thereby ethically acceptable remains ever valid. In order to be able to speak correctly of an ethics of artificial intelligence, it will therefore be necessary that the development of every algorithm always draws on an ethical vision, ‘algor-ethics’…”. You can read his remarks on AI in section 3 of his speech.


Regarding Lethal Autonomous Weapons, the Church continues to push for an international agreement to address the legal and ethical issues. In December 2021, the Holy See expressed its disappointment in the minimal progress made by a Group of Governmental Experts to begin negotiations for a binding instrument. Mgr John Putzer, chargé d’affaires of the Holy See Mission to the UN in Geneva, said that “it is imperative to ensure adequate, meaningful, and consistent human supervision over weapon systems” as “only humans are able to see the results of their actions and understand the connections between cause and effect”. Reiterating the Holy See’s call for a moratorium on the development and use of LAWS, he also proposed the establishment of an international organisation for AI, “to facilitate, and ensure the right of all States to participate in, the fullest possible exchange of scientific and technological information for peaceful uses and towards the common good of all the human family”.


The Catholic Union will continue to monitor developments in this area.
