Hopefully so but from what I understand, not at all in the US diocese. Maybe in Changanassery, but I hear that the Novus Ordo is alive and well in most of the other dioceses in Kerala.
ya its true but we canot blame the people for that because the reason is more historical
Metropolitan Archeparchy of Ernakulam-Angamaly.(Most latinized)
Metropolitan Archeparchy Changanassery.(Oriental)
Metropolitan Archeparchy of Kottayam.(Southist(Knanaya)Oriental)
Metropolitan Archeparchy of Tellicherry.(Oriental)
Metropolitan Archeparchy of Thrissur.(Partially Latin&partially oriental)
*Even Metropolitan Archeparchy of Thrissur were oriental up to AD 1850 .The Chaldean Patriarch Mar Joseph Audo sent two bishops. Mar Thoma Rocos came in 1861 and was sent away in 1862. Mar Yohanon Elia Mellus reached Trichur on 1874 and was compelled to leave in 1882.They resided in Trichur church(Marth mariam) that was built in 1814.
Upon his arrival in Kerala, Bishop Rocos applied himself to persuading the local Catholics of the regularity of his mission, saying that the Chaldean Patriarch had been ordered by the Holy See to consecrate him for the care of the Patriarch’s Christian communities. His fallacious claims weakened the faithful and were a source of great divisions. Soon, the majority of Syro-Malabar parishioners had left their rightful shepherd of the Latin rite, the Apostolic Vicar of Verapoly, in order to place themselves under the authority of the intruder bishop. Indeed, faithful and priests alike were very happy to welcome a bishop of their rite, whom they had hoped for for some time, and they supported Bishop Rocos’ aims and behavior as best they could. Of 154 Syro-Malabar parishes, 86 joined Bishop Rocos completely and another 30 partially; only 38 remained faithful to the legitimate authority.
Later, Patriarch Joseph VI Audo himself wrote from Rome to Bishop Rocos to request his return to Mesopotamia.
One Priest Anthony Thondanat had approached the Chaldean Patriarch Mar Joseph Audo, consecrator of Mar Thoma Rocos, to consecrate him as a metropolitan. The Latin authorities in Mosul did not permit the Patriarch to consecrate a bishop for India. That is the reason why he went to the mountains of Kurdistan, north of Mosul and requested Mar Ruwel Shimun Patriarch(Asyrian) to consecrate him. Priest Anthony was consecrated by the name Mar Abdisho in Mar Shallitha Cathedral in Kochanes (spelt Qudshanis).
But this created confusion among the Syro Malabar Christians and later some of the Syro Malabar Catholics(Less than 30,000 now) Accepted Priest Anthony as their bishop and became The Chaldean (Asyrians) church in India. And a series of court case started regarding the possession of churches between Catholics and Assyrians(Chaldean’s in India). Catholics won all the churches except one in Thrissur.So Catholics build a new church(Dolours basilica) near to their old church (Martha mariam church).This is the reason why Archeparchy of Thrissur is against the adoption of oriental(Chaldean) practices(To avoid any future claim by Assyrian or Chaldean patriarch over the the church in Malabar).
