There is a scheme like this for Hindus too, check this out:
Tamil Nadu CM’s decision to give grants for Hindu pilgrims: LETTER OF APPRECIATION FROM H.H. PARAMAHAMSA NITHYANANDA
(This letter of appreciation is in connection with the decision made by Hon’ble Tamil Nadu Chief Minister J. Jayalalitha Amma to allow grants for Hindu pilgrims travelling to the sacred destinations of Kailash-Manasarovar and Muktidham. The decision was announced on 14 May in the Tamil Nadu Legislative Assembly. A total of 500 Hindu pilgrims (250 each to Kailash-Manasarovar and Muktinath) will be given grants of Rs.40,000 each(for Kailash-Manasarovar pilgrims) and Rs. 10,000 each (for Muktinath pilgrims), which will cover 40% of their total travel costs to either destination. The selection of deserving applicants will be made by the Indian External Affairs Ministry.
Kailash-Manasarovar and Muktinath are much-revered Hindu pilgrimage centers, but out of reach for many financially challenged Hindus, as they lie outside the borders of present-day India, in China and Nepal respectively. The Hon’ble Tamil Nadu CM’s welcome decision will allow many more Hindus to make the trip to their dream spiritual destinations in future.)
But one thing though, the money for Hindu pilgrims comes out of temples revenue which is controlled by the Govt, and hence really is not a favour, if you think about it.
Churches on the other hand are not controlled, and on top of that get free grants from tax money
