When you read this please refrain from getting angry unless you have taken the time to study this subject in detail because here I only land on the surface and you need to dive to prove or disapprove but please not by conjecture, a good starting point will be with the works of Ianus that points at the Latin origin, the Lukan account, Harnack, even the controversial Knopf in Die Schriften des Neues Testament edited by Johannes Weiss and read Ramsay as well, this should be good starting point for your study.
The word Christian appears in the Bible three times in the verses of (Acts 11:26; Acts 26:28; and 1Pe 4:16). In Acts 11:26 is where we find the origin of the word when the Apostles where called Christians by the people of Antioch. Now many say that these people where converted Pagans that have accepted Christ Jesus as their saviour and others say they Jews, well neither is true and here is why.
Never did any apostle or even Jesus call the followers of Christ Christian or Christians but followers of Christ, brethren, the Way, etc. and this expels that notion. The Jews hated Jesus and would not acknowledge Him in anyway shape or form and they simply called the followers of Jesus the sect of the Nazarene. The Pagans called the apostles Christians in a derogative way and it meant little anointed or little Jesus’. It was not a term of endearment as they hated the followers of Christ Jesus as much and maybe even more that the Jews, it was only in the time of Constantine and the latter’s “vision “ that acceptance of the followers of Christ came with ulterior motives should be noted.
King Agrippa even joked about nearly becoming a “little Jesus” in the same derogative tone. In more modern times is the Roman Catholic Church that led the way with being derogative to the followers of Jesus. During the 1700 in France the name for the followers of Christ was etymologically derived from the stem Cretin:
1779, from French crétin (18c.), from Alpine dialect crestin, "a dwarfed and deformed idiot" of a type formerly found in families in the Alpine lands, a condition caused by a congenital deficiency of thyroid hormones, from Vulgar Latin *christianus "a Christian," a generic term for "anyone," but often with a sense of "poor fellow." Related: Cretinism (1801).
So a “Christian” is a dwarfed and deformed idiot, or as the Roman Catholics later softened it to “Poor Fellow”, poor in what, deformed health and mental idiocy, no wonder Christ Jesus did not call us “Christians”. Even today the Pagans still use the term derogatively, yes they are still Pagans.
I and my family are followers of Christ; we are brothers and sisters in the Body of Christ, the Church. We are the saints, disciples, brethren. We are not deformed Idiots we are men and woman of God, we are the followers of Christ Jesus our saviour!
