'Part' in the Bible

For to begin with, I hear that when you come together as a church there are divisions among you, and in part I believe it.

So the body is not one part but many.

And if they were all the same part, where would the body be?

For we know in part,and we prophesy in part.

For now we see indistinctly, as in a mirror,but then face to face.Now I know in part,but then I will know fully,as I am fully known.
