A fake story claiming that Pope Leo XIV has announced 15 major reforms has garnered considerable traction across the internet. The false claim is that Pope Leo has released a document called Cor Unum (“One Heart”), which allegedly contains sweeping changes to Catholic worship and governance.

One video circulating the rumour has more than 300,000 views on YouTube. It opens with the line: “Right now, as you are watching this, millions of Catholics around the world are waking up to a Church they no longer recognise…” and claims the 15 new reforms are “not a suggestion, not a proposal but a declaration”. Misled viewers have been quick to express their approval. One commented: “I'm watching from USA. OUR Lord Almighty bless our appointed Pope Leo. I am so grateful for all the new changes we will be having in our Churches,” while another wrote: “This pope is wonderful. What amazing changes!”
