The Syro-Malabar Qurbana on Sundays is basically the Divine Liturgy of Ss. Addai and Mari but just edited out a bit (solemn form) with Malabarese (Indian) traditions. The full form ( most solemn form) is the Raza Qurbana and this outline is not about the Raza Qurbana. The simple form is used on weekdays. So basically there’s 3 forms to the Qurbana: Raza, solemn, and simple form. The word Raza means mystery.
The word Qurbana means sacrifice or offering, so the Holy Qurbana means the Holy Sacrifice referring to the Passion, Death and Resurrection of Our Lord, Jesus Christ.
