(1) Almost every Rasool was a Nabi and almost every Nabi was a Rasool.
(2)A Nabi means receiver of a divine revelation/book meant to be held to by the people as proof and guidance from God.
(3)A Rasool is one who upon is to deliver clear message(s) from God and bring it down to the minds of the masses.
It's not the case that all of the message to be delivered must be words of God but can be teachings the Messenger paraphrases in his own words.
As for a Nabi, the book which is to be established as a proof from God, is God's words and not paraphrased by the Nabi.
A case when a Nabi is not a Messenger, is when, the messages are all established that God wants to be established on the masses, so the revelation just is revealed to verify the Prophet from God and to be guidance on top of guidance light on top of light.
A Messenger that is not a Nabi, is when messages of God need to be revived in the minds of the people paraphrased in the Messengers own words, but no revelation is revealed to the people by that Messenger.
The 12 Imams are all Messengers but none of them is a Nabi for example.
Now to prove this we can simply quote one verse 5:67. According to 5:67, there was something revealed that Mohammad (pbuh&hf) was suppose to deliver and convey and if he didn't, he didn't convey the message.
Because jump if you didn't jump you didn't jump is meaningless, we can derive:
(1) This cannot be saying "recite the Quran if you don't recite it all, you have not recited it all", so what God revealed here doesn't refer to delivering a Quranic verse.
(2) It's saying you need to convey a major thing God has revealed, and according to history, this was regarding the Wilayah of Ali and Ghadeer.
(3) We can see here, Resalah is not just Quran. So resalah is conveying here something in Quran to the minds of all people through out time but paraphrased in the words of Ghadeer speech.
(4) This is despite Wilayah of Ali and Ahlulbayt clear in Quran, it's saying, ignorance and sorcery has befallen your people and blindness to Ali might take upon humanity, deliver a speech to convey it to all generations, that Ali has your Wilayah over humanity and that this the weight of Quran and your family, two weights as a single unit - the rope of God.
The Prophet conveyed such a way, that, manifest the chosen family theme of Quran and manifest the position of Ali and Fatima.
Like wise, Ahlulbayt, conveyed words, that revive Quran and manifest much of Quran. They are delivering messages from God regarding what God revealed, but paraphrased in their own way.
