Soon after liberation there were changes in Catholic rituals which took place globally as well as in the church in Goa. It was a follow up to the post vatican changes effected in the liturgy. The church began to use the vernacular instead of the Latin church dialect. In Goa, a movement began in the corridors of the seminary to change existing Latin to vernacular kokani. It is decided in this article, to demonstrate this with rest to two classical masterpieces of the church, that is, tantum ergo and o salutaris. Addition will follow tomorrow.
