An Eastern Catholic Church based in India, practicing an East Syriac Rite and following the traditions of St. Thomas the Apostle. It is one of the 23 sui juris (self-governed) Eastern Catholic Churches in full communion with the Holy See.
According to tradition, Our Lady appeared to a few shepherd children at Kuravilangad as they were tending their flock. She asked them to build a church at the place from where a miraculous perpetual spring sprouted, which exists even today. The children reported this matter to the elders and a church was built there.
