About Eastern Catholicism…
Eastern Catholic (EC) churches vary in their traditions and spirituality. Because they are in communion with the Pope and the Latin Church, some will have that Latin influence on them and will be latinized. And others will go the opposite way and try to stay true to their original traditions (so say for example if it’s Byzantine Rite Catholic- they would try to be as close to be like the Eastern Orthodox).
I’m from the Syro-Malabar Church (SMC), we employ the East Syriac Rite liturgy. We are unique in that our counterpart is the Assyrian Church of the East (Not Orthodox -not in either OO or EO communion). The Assyrian Church tried to be in communion with the Syriac Orthodox back in the late 90s- but it failed through. The Coptic Pope who is the supposed head of all OO churches had disagreements and the Assyrian Church didn’t agree w/ some things.
The SMC was under Latin jurisdiction from 1599 (Synod of Diamper) till 1887 when Pope Leo XIII separated us from Latins. Your average SMC laity is heavily latinized. So much so that back in India, your average laity would call themselves “RC” for “Roman Catholic”. Whether me, my parents or grandparents, we were taught prayers such as the angelus, rosary, litany of BVM, and the divine chaplet- which are all part of Latin spirituality.
For the pro-Latin faction within the SMC- it’s a matter about identity. Are we Catholic (Latin) or East Syriacs? pro-Latin eparchies do the Mass just like the Ordinary form (OF). externally it would look just like the OF. The problem with the Church of the East (CoE) was that it was considered heretical by both EO/OOs and Rome. It’s the odd one among the apostolic churches, and they are currently a dying church. So for the pro-Latin SMCs breaking communion with Rome or being like the CoE doesn’t make much sense.
On the other hand- the other EC church in India- the Malankara Syrian Catholic Church - has had it more easy to stay true to their traditions possibly because 1. they joined in communion w Rome in 1930, rather recent and 2. their counterpart churches are OO - Syriac Orthodox and Malankara Orthodox churches.
