1 Cor. 12:13 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. 1. "by" on Spirit means "by his leadership" or "under his direction" 2 Ye know that ye were Gentiles, carried away unto these dumb idols, even as ye were led. 3 Wherefore I give you to understand, that no man speaking by the Spirit of God calleth Jesus accursed: and that no man can say that Jesus is the Lord, but by the Holy Ghost. This section introduces the Greek preposition "en" in connection with the Spirit in verses 2-3 in contrast to the phrase "as ye were led." When they were lost they were UNDER THE LEADERSHIP of demons but when God saved them they came under NEW LEADERSHIP and this contrast of leadership is expressed by introducing "en" in contrast to that phrase. Under the leadership of the Holy Spirit no man can call Jesus accursed and no man can call Him Lord in its Biblical sense except UNDER THE LEADERSHIP "by" the Spirit. The same meaning is restrained throughout this passage right to its use in verse 13. So verse 13 refers to the LEADERSHIP of the Spirit. By or under the Leadership of the Spirit the members had been baptized into one body. This idea of "under leadership" by the Spirit was first introduced in 1 Cor. 3:5-16 where the building of the congregation at Corinth is explained to have taken place under certain conditions. The human instruments that brought the gospel and water baptized them into this congregation were working in unity under the leadership of the Spirit of God in building a temple at Corinth: 1 Cor. 3:8 Now he that planteth and he that watereth are one: and every man shall receive his own reward according to his own labour. 9 For we are labourers together with God: ye are God’s husbandry, ye are God’s building. That is the human instruments that administered water baptism to these members were working together as "one" under the leadership of the Spirit so that it was the Holy Spirit who actually saved them and water baptized them into that "building" at Corinth. He did not say "we" are God's husbandry and building but "ye" are. He is talking about how the church at Corinth was built under the leadership of God the Holy Spirit as a "temple" (1 Cor. 3:16). His reason for informing them of this is because they were bragging and dividing themselves under these different human instruments (1 Cor. 1:11-13): 1 Cor. 1:11 For it hath been declared unto me of you, my brethren, by them which are of the house of Chloe, that there are contentions among you. 12 Now this I say, that every one of you saith, I am of Paul; and I of Apollos; and I of Cephas; and I of Christ. 13 Is Christ divided? was Paul crucified for you? or were ye baptized in the name of Paul? What they were doing about baptism they were doing about spiritual gifts. They were boasting in one gift over another. They all partook of that ONE TEMPLE/BODY at Corinth by being led by One Spirit to be water baptized into that congregation. Likewise, they partook of the gifts of the Holy Spirit who dwelt in that congregational body as His "building" and "temple" and "body" under the leadership of that same Spirit who equipped and set them in that body as it pleased him (vv. 14-26) so that "YE are the body of Christ and members in particular" at Corinth (v. 27) and this is precisely what he does in regard to the institutional body of Christ whenever and wherever He builds them. CONCLUSION: 1 Cor. 12:13 simply summarizes his exposition and response to their division over differences in baptismal administrators in 1 Cor. 3:5-16 and then applied to the same problem of differences over spiritual gifts in the church body at Corinth in 1 Cor. 12.
