As someone who comes from a Christian background in India I would like to add here that while the caste system (unfortunately) exists even among the Christians and Muslims in India it is nowhere near as strong as among the Hindus.
There are indeed situations where in parts of the country there are even cemeteries divided on the basis of caste but this is far from being the norm.
However, there are many low caste priests and even bishops in Christianity - which is a very rare occurrance among Hindus where priests are almost exclusively brahmin except for very rare exceptions.
Christianity in India has a fascinating history. The first were converted by Saint Thomas the Apostle personally. And then Christian missionaries were part of the much more recent European contact. I’m no expert on the subject, but I’d wager how Christians in India see caste depends on their particular heritage.
