Catholics are the followers of Christian Faith founded by Jesus and his Apostles, the chief being Simon Peter. The Vatican is the Head of the Roman Catholic Church who is vested with powers ordained by the Lord to preside over all matters pertaining to the Catholic faith.

In India, there are different sects of Catholic faith like the Syrian Christians of Malabar, Anglo Indians, Goan Christians they could be of different sects, affiliated to different parishes but they are essentially Catholics whose head is the Vatican. Unlike Hindu marriages where horoscopes are compared for a suitable match, in Catholic weddings, Church is the central point. There is a marriage registry in the Church where one can register for a bride or a groom. This registry is networked among other parishes affiliated to a Cathedral.
