New Defender's Study Bible Notes
1:3 fellowship. “Fellowship” as used in Scripture does not refer to mere social companionship or camaraderie, as we tend to use the term today. The same word is translated “communion” (e.g., I Corinthians 10:16; II Corinthians 6:14). The basic meaning is “joint participation in things held in common.” The fellowship we can have with the Father through the Son (John 17:22,26) is the same fellowship we as believers can have with one another.
