Answer:
The answer is option A.
Step-by-step explanation:
A Catholic mass comprises of two primary parts: the Proper, which changes from Sunday to Sunday, and the Ordinary, or, in other words consistently. The Catholic Church sees the Mass or Eucharist as "the source and summit of the Christian life", to which alternate holy observances are situated. The Catholic Church trusts that the Mass is the very same forfeit that Jesus Christ offered on the Cross at Calvary.
