Easton's Bible Dictionary (1897)
Fellowship with God (Gen. 18:17-33; Ex. 33:9-11; Num. 12:7, 8), between Christ and his people (John 14:23), by the Spirit (2 Cor. 13:14; Phil. 2:1), of believers with one another (Eph. 4:1-6). The Lord’s Supper is so called (1 Cor. 10:16, 17), because in it there is fellowship between Christ and his disciples, and of the disciples with one another.
