In reading through an excellent book on George Washington's interim years between the War and his presidency (Edward J. Larson's The Return of George Washington), I've been struck by his building, burning desire that a Constitution should be composed in order to solidify a national union of the states. His fear was that the disparate parts would become so disunited that the War with England would've been for naught...
The Church's Constitution has already been composed - it's Jesus, the Word Incarnate - and our "states" are the individual members of the Body of Christ. Our personal Union with Jesus constitutes the only path to Union in the Body; we will only be one with each other as we are one with Him.
It's Union or nothing. There is no middle path except the straight and narrow.
