There are four descriptions about the institution of the Holy Qurbana in the New Testament:
1. Mt:26:26-28
2. Mk:14:22-24
3. Lk:22:17-20
4. I Cor:11:23-25

The testimony of St.John deserves special sttention. John 6:53 says Jesus Said to them: "I tell you the truth, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you".
