Are there any major Eastern Catholic missionary societies that proselytise among Protestants, non-Christians, etc.?
The Malankara Syriac ‘Order of the Imitation of Christ’ and ‘Daughters of Mary’ do missionary work among non-Catholics, proselytizing is not done. The missionary work, charitable actions, and educational opportunities have resulted in converts from other faiths/religions.
Where do they operate? Is it mostly around Kerala, where the Malankara church is centered?
