'Fellowship' in the Bible

And when James, Cephas, and John, who seemed to be pillars, perceived the grace that was given unto me, they gave to me and Barnabas the right hands of fellowship; that we should go unto the heathen, and they unto the circumcision.

So then those who are people of faith [whether Jew or Gentile] are blessed and favored by God [and declared free of the guilt of sin and its penalty, and placed in right standing with Him] along with Abraham, the believer.

But if you bite and devour one another [in bickering and strife], watch out that you [along with your entire fellowship] are not consumed by one another.
