So I am sure you are aware that with the coming of Jesus Christ, an individual’s enjoying a proper relationship with God and approaching him acceptably in prayer depended on acceptance of Jesus Christ. As the Son of God stated: “I am the way and the truth and the life. No one comes to the Father except through me.” (Joh 14:6; Heb 10:19-22) Those who became followers of Jesus Christ were spoken of as belonging to “The Way,” that is, they adhered to a way or manner of life that centered around faith in Jesus Christ, following his example. The Latinized Greek term Khri•sti•a•nos′, found only three times in the Christian Greek Scriptures, designates followers of Christ Jesus, the exponents of Christianity.—Ac 11:26; 26:28; 1Pe 4:16.
As I mentioned in my previous comment
,// “It was first in Antioch [Syria] that the disciples were by divine providence called Christians.” (Ac 11:26) It is possible, then, that this name was used as early as the year 44 C.E. when the events surrounding this text occurred, although the grammatical structure of this phrase does not necessarily make it so; some think it was a little later. At any rate, by about 58 C.E., in the city of Caesarea, the term was well known and used even by public officials, for at that time King Herod Agrippa II said to Paul: “In a short time you would persuade me to become a Christian.”—Ac 26:28.//
It is most unlikely that the Jews first styled Jesus’ followers “Christians” (Greek) or “Messianists” (Hebrew), for they would not reject Jesus as being the Messiah, or Christ, and then tacitly recognize him as the Anointed One, or Christ, by stamping his followers “Christians.” Possibly the heathen population may have nicknamed them Christians out of jest or scorn, but the Bible shows that it was a God-given name; they “were by divine providence called Christians.”—Ac 11:26.
Yes, they were Jews, but Jesus’ teachings showed them up as not being true worshippers of God – hence on Jesus’ death, the Mosaic Law became obsolete – a new law “The Kingly Law” came into operation.
