1Co 12:14 For the body is not one member, but many.
When we have a description of the Church as a body, we must recognise many aspects of such a concept in order to minister to it and through it. The lack of understanding of the body and its parts (members) is the prime reason for criticism of the Church. Anyone who looks at their own body and criticises it is not wise. On the contrary, one must honour the body parts. 1Co_12:23 And those members of the body, which we think to be less honourable, upon these we bestow more abundant honour; and our uncomely parts have more abundant comeliness.
So, what do we know about the spiritual body of Christ?
The body is both local and worldwide
A body has many members
The parts are different to each other in appearance
Their functions are different
They all belong in the body
Some are stronger than the others
They work together for the good of the body
No one member is greater than the other as they all belong in one body
Each body part is held together by their common purpose and reason for existence
If one suffers, all suffer. If one rejoices, all rejoice.
