In 1 Corinthians 12:13, is the Spirit the Holy Spirit?
In 1 Corinthians 12:13, the Spirit is the Holy Spirit. The term 'Spirit' is capitalized, identifying Him as the Holy Spirit. The verse states that by one Spirit all believers are baptized into the body of Christ, which is the Holy Spirit's work.
Les teaches that in 1 Corinthians 12, Paul gives a beautiful description of the body of Christ, which is a Pauline term and doctrine. Jesus never referred to believers as His body. Les points out that in verse 13 the word 'Spirit' is capitalized, so it is the Holy Spirit. He emphasizes that 'by one Spirit' all believers—not just the most spiritual or holy—are baptized by the Holy Spirit into the body of Christ. Les also notes that this spiritual baptism is not something human hands can touch.
For by one Spirit are we all baptized into one body, whether we be Jews or Gentiles, whether we be bond or free; and have been all made to drink into one Spirit.
