What is the difference in meaning between “fellowship” in 1 Corinthians 1:9 & “communion” in 2 Corinthians 13:14?
1 Corinthians 1:9
9 God is faithful, by whom ye were called unto the fellowship of his Son Jesus Christ our Lord. KJV, ©1769
Θʹ πιστὸς ὁ θεὸς δι᾽ οὗ ἐκλήθητε εἰς κοινωνίαν τοῦ υἱοῦ αὐτοῦ Ἰησοῦ Χριστοῦ τοῦ κυρίου ἡμῶν TR, 1550
2 Corinthians 13:14
14 The grace of the Lord Jesus Christ, and the love of God, and the communion of the Holy Ghost, be with you all. Amen. KJV, ©1769
ΙΔʹ Ἡ χάρις τοῦ Κυρίου Ἰησοῦ Χριστοῦ καὶ ἡ ἀγάπη τοῦ Θεοῦ καὶ ἡ κοινωνία τοῦ Ἁγίου Πνεύματος μετὰ πάντων ὑμῶν ἀμήν. TR, 1550
So why are two different words used in King James Version (ed. 1769)? Is there any real difference?
Also, what is the meaning of these words? What happens in and during fellowship or communion? What are the benefits of fellowship or communion?
