In those days, all unbelievers were 'MEMBERS OF GREEK CIVILIZATION' (everybody else was a JEW), but for those who are spiritually IN JESUS (spiritually living INside the body that hung on the cross, the body that became the new worship temple, John 2:21), there are NO JEWS at all, neither are there any "Greeks" (Gentiles....unbelievers)...
Galatians 3:28 "neither Jew nor Greek". .......(spirits inside Jesus don't have any GENDER either ,...."neither male nor female").
The Jews were baptized into MOSES, we are baptized into JESUS (this must be clearly understood)...
1 Corinthians 10:2 "and all were baptized into Moses".
In Acts 11:26 "and in Antioch the disciples were first called Christians".
The "Incident at Antioch" (Hebrew followers of the promised Messiah) is referred to in that verse.
The chief Pharisee (SAUL) persecuted the followers of Jesus (Acts 9:2, "THE WAY"). Paul was never a "Christian" (Acts 19:9 and other verses).
The Council of Jerusalem was around 50 A.D (17 years after the crucifixion).
Neither the word "Christianity" nor the word "bible" are in scripture at all, The word "Christian" is used twice, the word "Christians" only once.
Jesus characterized Peter the denier by saying that Peter was not on the side of God....
Mark 8:33 "But turning and seeing his disciples, he rebuked Peter, and said, "Get behind me, Satan! For you are not on the side of God, but of men".
The Hebrew "Christians" never advanced their devotion to a state of "maturity" (Hebrews 6:1) but remained as "babes in Christ" (1 Corinthians 3:1) with only a "faith TOWARD God", but not a "faith FOR FAITH" (Romans 1:17, Hebrews 11:6). They were taught ("fed") "milk", but never moved on to "solid food"... . 1 Corinthians 3:2 "I fed you with milk, not solid food, for you were not ready for it, and even yet you are not ready".
There are many differences ("depths of God", 1 Corinthians 2:10) between a Jewish Messianic devotion and the devotion of a "True worshiper" (John 4:23).
The "strong delusion" is not a future event. SAUL (the chief Pharisee) persecuted the true followers of Jesus....Acts 9:2.
John 14:6 "I am THE WAY...".
