Here is a brief excerpt:

John Piper explains why it’s good to have a church covenant even if church covenants aren’t in the Bible:

The Bible does not say explicitly, “Thou shalt have a written church covenant,” any more than it says, “Thou shalt have marriage licenses,” or, “Thou shalt have wedding rings.” . . .

One way to look at it is that a church without a covenant is like a marriage without vows. Marriage vows are not spelled out in the Bible just like church covenants aren’t. Both follow necessarily from the nature of the relationships.
