I also had the fortune of witnessing a quarrel among Christians regarding castes (they use a different word, something like dominion). Two Christians abused each other about their "castes". One was from Pentecostal and another was some other "caste".
I know one Christian who says that their ancestors were Syrians, and they are Syrian Christians and they are not Indian Christians. But this guy looks very, very Indian with dark complexion and normal Indian facial features.
