Or, do you not know that the person who is joined to a prostitute is one body [with her, physically]? For God says [Gen. 2:24], "The two will become one flesh" [i.e., united in such a close relationship as to practically constitute one body].

For we were all immersed by means of the one Holy Spirit into one body [i.e., the church], whether [we were] Jews or Greeks [i.e., Gentiles], whether slaves or free people, and were all given the one [and the same] Holy Spirit to drink. [Note: This probably refers to the indwelling of the Holy Spirit, given to all immersed believers. See John 7:37-39; Acts 2:38].

So, if one part [i.e., one Christian] suffers, then all the parts [i.e., the other Christians] should suffer with it. Or, if one part is honored, all the [other] parts should rejoice with it.
