" In modern church life, we often leave the nave to have "fellowship" with one another at social functions in the basement, and we are sometimes invited to "fun and fellowship" at games nights or congregational picnics. These are inappropriate usages of the word "fellowship" (which translates the New Testament κοινωνία), for the human interaction that takes place in church basements and public parks can be shared without a qualm with Christians of other confession and even with the irreligious and pagans. True κοινωνία begins with baptismal admission into the church (δι' οὗ ἐκλήθητε εἰς κοινωνίαν τοῦ υἱοῦ αὐτοῦ 'Ιησοῦ Χριστοῦ τοῦ κυρίου ἡμῶν, 1 Cor 1:9) and culminates in the fellowship granted through common partaking of the holy things; as such, it is entirely distinct from all Adamic-earthly gatherings, being the supernatural product of divine monergism.
