Are the words 'was made' in 1 Corinthians 15:45 original?
No. The words 'was made' in 1 Corinthians 15:45 are italicized, indicating they were added by translators rather than being original. The text would better read without them: 'the last Adam a quickening spirit,' meaning Christ is a life-giving spirit.
Les explains that in 1 Corinthians 15:45, the phrase 'the first man Adam was made a living soul' points back to Genesis 2, where God breathed into Adam the breath of life. Then the verse speaks of 'the last Adam,' who is Jesus the Christ. Les points out that the word 'was made' in the second half is italicized, showing it was added by the translators. He thinks it is better left out, so the text reads 'the last Adam a quickening spirit.' Quickening means life-giving, as in Ephesians 2:1, where those dead in trespasses and sins are quickened, made alive.
And so it is written, The first man Adam was made a living soul; the last Adam was made a quickening spirit.
