member

Definition:

The term "member" refers to one part of a complex body or group.

The New Testament describes Christians as "members" of the body of Christ. Believers in Christ belong to a group that is made up of many members.
Jesus Christ is the "head" of the body and individual believers function as the members of the body. The Holy Spirit gives each member of the body a special role to help the entire body to function well.
Individuals who participate in groups such as the Jewish Council and the Pharisees are also called "members" of these groups.
