“Life ‘in Christ’ is clearly not just a one-to-one relationship, but one that binds individual believers together into a single community. Christians have been made members of a single family by their baptism in Christ. Because they are all ‘sons of God’, Paul tells the Galatians, ‘there is no longer Jew or Greek, no longer slave or free, no longer male and female. For you are all one in Christ Jesus’ (Gal. 3:26-8). Elsewhere, he likens this community of believers to a body, whose welfare depends on the contribution made by individual members (Rom. 12:3-13; 1 Cor. 12:4-31).
He also refers to the Christian community as a temple, and since the temple was regarded as God’s earthly dwelling, the image is an apt one: they are God’s temple because God’s Spirit lives within them, and if God’s Spirit lives in them, they must be holy (1 Cor. 3:16-17, 2 Cor. 6:16-18). All these images – family, body, temple – imply life, fellowship and growth, rather than an organized structure.” (Morna D. Hooker, Paul: A Beginners Guide, pgs. 132-133)
