Luke 6:13 says “And when it was day, he called unto him his disciples: and of them he chose twelve, whom also he named apostles.” The word used for apostle is ἀποστόλους (apostolous) which only means “delegate.” It was mistakenly thought to be a position of authority by others which is not the fault of Jesus. Jesus meant them to excel in unselfish service with no expectation. (Luke 22:24-26)
Interestingly, apostles were all married and they were all accompanying them in ministry. (1 Corinthians 9:5) Luke 10:1 says: “After this the Lord appointed seventy-two[a] others and sent them two by two ahead of him to every town and place where he was about to go.” When this is read with 1 Corinthians 9:5 it would mean Jesus sent them as couple, husband and wife, as equal partners, as God originally meant them to be. (Genesis 5:1; Mathew 19:4-6)
