Our Lord at the church in Capernaum just before the Holy Qurbana is instituted at the Sehiyon Mansion of St.Mark, foretold the importance, the purpose and the necessity of it sufficiently early. (John 6:26-59).

It has five purposes:
1. For the remission of sins (Math.26:28)
2. For life (John 6:51)
3. For everlasting life (John 6:54)
4. For resurrection (John 5:28-29)
5. For God to remain in us (John 6:56)
