It looks like Mother Teresa will be made a saint next year.
Pope Francis has recognised a second miracle it's believed she was involved in. A Brazilian man with several brain tumours was healed in 2008.
Mother Teresa died in 1997 and was beatified - the first step towards sainthood - in 2003.
"The Holy Father has authorised the Congregation for the Causes of Saints to proclaim the decree concerning the miracle attributed to the intercession of blessed Mother Teresa," the Vatican said on Friday.
She is expected to be made a saint in Rome in September.
