From Aleteia:
The small town of Eten in the province of Chiclayo, in northern Peru, is best known for a purported Eucharistic miracle. The phenomenon is said to have taken place twice, on June 2 and July 22, 1649. On those dates, the face of the Baby Jesus is said to have appeared on a consecrated host during major religious celebrations.
Although the Catholic Church has not officially recognized the phenomenon, the election of Pope Leo XIV — former bishop of Chiclayo — has given the population new hope. Many see him as the man designated by Divine Providence to finally bring recognition to this miracle that is more than three centuries old. Carlo Acutis included this miracle on his website about Eucharistic miracles; we can still visit the page today, even in an English translation!
