They were Jews by nationality.They were called Christians by name but the most were Jews by nationality, and all the Apostles including Jesus were Jews by birth. Definitely not Roman Catholics LOL.
But not by religion.
Indeed Jewish is BOTH a nationality AND a religion.
By the time the bible was put together,,,the 400's about,,,the Jews by religion were known as Christians.
Agreed.Umm, the Bereans when confronted by those who should have known (i.e. the Apostles) still checked the Old Testament to see if these things were so.
Acts 17:11 (KJV) These were more noble than those in Thessalonica, in that they received the word with all readiness of mind, and searched the scriptures daily, whether those things were so.
...that is how we are to treat all teachings
