I was reading a story about St. Jacob of Hamatoura, and I was surprised to read that there are apparitions of him. For those who might not know his story, St. Jacob was an abbot who lived in the 15th century, and rebuilt the formerly destroyed Our Lady at Hamatoura Monastery. He was captured and tortured by Muslims who wanted him to renounce Christianity and convert to Islam. He was eventually martyred and his body burned. He was lost to history until 2002 when a document was found identifying him as a saint, but Christians reportedly claimed a monk appeared to them in the monastery before then, and that he performed miracles. While the writing never claims this to be St. Jacob, it’s heavily implied.
I know that the Church teaches that Jesus and Mary have certainly appeared to individuals, but this was the first time I had heard about a saint other than Mary having any reported apparitions. I was unable to find much more information on this topic, so I wanted to ask if saints do, in fact, make posthumous appearances to individuals.
