In the knowledge economy and problem solving enterprise of the 21st century, Artificial Intelligence (AI) is gradually being embraced and becoming a valuable tool in the minds and hands of different institutions either as a nation, an organisation/company or even as an individual, as the AI skills are being integrated in public relations and development of the human society. The religious institutions and bodies are not left out in the uses and benefits of AI in their various activities relating to different publics. The Catholic Church identifies and relates with her publics – the innovators and end users. The letter of Pope Francis, written to celebrate the 2024 World Communication Day, formed the working document for this paper as it was surveyed and some interpretative commentary given. It highlighted the genuine fears and concerns of the evils and disadvantages of AI to the human person and its relations as they point to social isolation, cognitive pollution, creating group-thinking among other issues. The paper also adopted the survey researches done by Gartner Incorporated and Oluwadiya et al. (2023). The findings revealed and corroborated the position of the Catholic Church that AI without ethics gradually diminishes humanity (human intelligence and communication). Thus, the development and usage of AI should be with the wisdom of the heart and geared towards a fully human communication.
