For as the body is one and has many members, but all the members of that one body, being many, are one body, so also is Christ. For by one Spirit we were all baptized into one body—whether Jews or Greeks, whether slaves or free—and have all been made to drink into one Spirit.
The apostle Paul compared the Church of God to a human body, with each part intricately linked to the others. It is through the gift of the Holy Spirit after baptism that members of God’s Church are put into that Body. Paul tells the Corinthian members that our human circumstances are not to affect the unity God intends for us to have. While the Jews and Greeks were separated by society’s norms around them, and the gulf between the status of slaves and free people was large, God’s Spirit bridges all these gaps.
