Tread carefully when discounting quotes from Jesus (AKA The Word).
"Discounting" what do you mean by that?
Everything past verse 7 in
Mark 16 is highly suspect.
This is not tearing down Scripture; rather it is discussing a fact well-known among Bible students. Dan Wallace suggests that there a total of 5 different endings for Mark, and that three of them can be "easily eliminated".
He also stated:

In verse 17, ‘and these signs will accompany those who believe: in my name they will drive out demons, they will speak in new tongues, they will pick up snakes with their hands; and when they drink deadly poison, it will not hurt them at all; they will place their hands on sick people, and they will be healed. After the Lord Jesus had spoken to them, he was taken up into heaven and he sat at the right hand of God. Then the disciples went out and preached everywhere, and the Lord worked with them and confirmed his word by the signs that accompanied it.’ It is verses 17 and 18 especially that are problematic for a lot of Christians...
In terms of the external evidence. At least ninety five percent of all manuscripts versions and fathers have the long ending. That is very huge; that is a lot, but we have said all along that we don’t count manuscripts, but instead we weigh them. It is also found as early as the late 4th or early 5th century in Codex W...
For Codex Vaticanus, it has an entire blank column at the end for Mark and it is the only blank column in the New Testament of the manuscript. Does this indicate that the scribe knew of the longer ending and was making room for it? Unlikely, since there isn’t room for the long ending. It is also unlikely that this is what the scribe was doing as there are three Old Testament leafs that have a blank column...
Summary
So, why did this Gospel have such a major textual upheaval at the end of the book? It was because scribes weren’t comfortable with a Gospel ending without any resurrection appearances. This seems to make the most sense by far. If Mark 16:9-20 was original then why would the material be deleted? Why don’t any manuscripts delete the ending of Matthew, Luke or John? If the material was offensive, why would not they delete verses 17 and 18? So to conclude the external evidence, but I brought in the internal as well.

As for this, "quotes from Jesus (AKA The Word) " I have no idea what you mean. It is not wrong to discuss what now exists regarding the last part of Mark 16, and to propose some reasons for those 5 possible endings. Those variations are facts, and they will not go away because we may wish them to disappear.
Those variations do not demean Jesus Christ in any way nor do they change the text.
Britannica says this:
It is attributed to John Mark (Acts 12:12; 15:37), an associate of Paul and a disciple of Peter, whose teachings the Gospel may reflect. It is the shortest and the earliest of the four Gospels, presumably written during the decade preceding the destruction of Jerusalem in AD 70. Most scholars agree that it was used by Matthew and Luke in composing their accounts; more than 90 percent of the content of Mark's Gospel appears in Matthew's, and more than 50 percent in the Gospel of Luke. Although the text lacks literary polish, it is simple and direct; and, as the earliest Gospel, it is the primary source of information about the ministry of Jesus.

According to the above, Mark wrote his Synoptic Gospel c. 60 AD. That is about 30 years after the Crucifixion and Resurrection of Jesus Christ
Therefore, it was a few scribes who for one good reason or not changed that part of Mark 16. This is a matter of transmission of the Bible and in no way changes the central, core beliefs of Christianity.
It is my hope that this clarifies some things about the endings of Mark 16, and that it calms you.
