1Corinthians 15:4c-8 And that he was seen of Cephas, then of the twelve: After that, he was seen of above five hundred brethren at once; of whom the greater part remain unto this present, but some are fallen asleep. After that, he was seen of James; then of all the apostles. And last of all he was seen of me also, as of one born out of due time.
‘Seen’ – Over 514 witnesses saw Christ after the resurrection, we have 12 appearances of Christ: firstly to Mary Magdalene (Mark 16:9; John 20:15-16); to the women at the tomb (Matt. 28:9); to two disciples on the road to Emmaus (Luke 24:13-31); to Peter (15:5; Luke 24:34); to ten of the apostles (John 20:19); to eleven of the apostles (John 20:26); to seven of the apostles (John 21:1-22; this was after the second Sunday); to eleven of the apostles on a certain mountain in Galilee (Matt. 28:16); to all twelve apostles, which including Matthias (15:5; Acts 1:26); to five hundred brethren (15:6); to James, the Lord’s brother (15:7; Gal. 1:19); to all the apostles again (15:7; Mark 16:19-20; Luke 24:50-53; Acts 1:3-12, 26).
‘Cephas’ this was Peter (Luke 24:34; Mark 16:14).
‘The twelve’ – the term is used here officially, including Matthias (Acts 1:26) and excluding Paul (15:7-8).
‘He was seen of above five hundred brethren at once; of whom the greater part remain unto this present, but some are fallen asleep.’ This could be the same as in Matthew 28:16.
‘He was seen of James; then of all the apostles.’ This is James, the half-brother of Jesus (Gal. 1:19).
‘And last of all he was seen of me also’ – This is proof that Paul did not class himself as one of the 12 apostles (15:5-8). They were chosen because they had been eyewitnesses from the beginning.
‘One born out of due time’ [Greek: ektroma] a child untimely born; an abortion. Paul referred to being born out of the season when the 12 apostles were chosen (Isa. 66:6-7; Rom. 11:25-29; Zech. 12:10-13:1).
