Since ‘Christianity’ was just a nickname given by unbelievers long after Christs death, and it was even first given to people who didn’t preach to other than JEWS! IE ONLY preached to JEWS.

(The christening of ‘Christianity’ in the Bible, years AD.)

Acts 11:19-26 –
19 … preaching the word to none but unto the Jews only. …26…And it came to pass, that a whole year they assembled themselves with the church, and taught much people. And the disciples were called Christians first in Antioch

The only name that seems appropriate for the faith of Christ, that was mentioned in the Bible is-

‘Peace/ Salem/ Salam/ (Islam in Arabic)’

He(Jesus) said in his parting speech, that what he leaves with us is ‘Peace!’ So that’s the most logical name of the Faith he left!

Joh 14:27 –
Peace I leave with you, my peace I give unto you: not as the world giveth (a special different ‘Peace’ gift), give I unto you. Let not your heart be troubled, neither let it be afraid.

Other references that indicate ‘peace’ Being the name of Jesus’ creed-

Heb 6:20 –
where Jesus has entered as a forerunner for us, having become a high priest forever according to the order of Melchizedek.
And what was the order of Melchizedek/ What was his kingdon that Christ came according to?…

Heb 7:2 –
Melchizedek..To whom also Abraham gave a tenth part of all; first being by interpretation King of righteousness, and after that also King of Salem, which is, King of peace

Hebrews 7:1-10 –
1 For this Melchizedek, king of Salem/salam/Peace/Islam, priest of the Most High God, who met Abraham as he was returning from the slaughter of the kings and blessed him, 2 to whom also Abraham apportioned a tenth part of all the spoils, was first of all, by the translation of his name, king of righteousness, and then also king of Salem, which is king of peace. 3 Without father, without mother, without genealogy, having neither beginning of days nor end of life, but made like the Son of God, he remains a priest perpetually
Ge 14:18 –
And Melchizedek king of Salem/Peace

Another common description of Jesus:
Isa 9:6 –
For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be ………. The Prince of Peace

It is so funny how we seemingly intentionally ignore thes obvious facts. I am sure Jesus would appreciate it better if we are referred to by more than a nickname. Jesus didnt come to do all that work for us, and then simply forget to christen his gift!

He called his gift- ‘PEACE’!, not the ‘Peace‘ we were used to. He was a priest and king also as was/is Melchizedek, of Peace. Jesus was the prince of peace and we also are followers of peace.
