Pope Leo has made a historic apology for the Catholic Church's involvement in slavery, recognizing the institution's failure to denounce the practice for centuries. In his first papal encyclical, titled *Magnifica Humanitas*, he referred to slavery as 'a wound in Christian memory' and expressed deep sorrow for the suffering endured by enslaved individuals. Leo acknowledged that the Church had, at times, legitimized slavery and only issued a formal condemnation in the 19th century under Pope Leo XIII. This apology is significant as it represents the most explicit admission of institutional responsibility by a pope, contrasting with earlier statements from previous popes that focused on individual Christians. Additionally, Leo's encyclical addresses modern ethical challenges posed by artificial intelligence and the need for regulatory frameworks to mitigate risks associated with new technologies. He also criticized the outdated 'just war' theory, arguing that it has been misused to justify conflicts, and expressed concerns about leaders potentially using war as a distraction from domestic issues.
