Hello,
Ministry of minority affairs include muslims, sikhs, christians, buddhists, Parsis and jains notified as minority communities in The Gazette of India (https://en.m.wikipedia.org/wiki/The_Gazette_of_India) under Section 2(c) of the National Commission for Minorities Act, 1992.
Nothing is specifically written about Roman Catholics that I know of.
