'Members' in the Bible

[it is this:] that the Gentiles are now joint heirs [with the Jews] and members of the same body, and joint partakers [sharing] in the [same divine] promise in Christ Jesus through [their faith in] the good news [of salvation].

Therefore, rejecting all falsehood [whether lying, defrauding, telling half-truths, spreading rumors, any such as these], speak truth each one with his neighbor, for we are all parts of one another [and we are all parts of the body of Christ].

because we are members (parts) of His body.
