You did not answer my point. It is not debating just to say, "No, I'm right."
I logically referenced how the ending of Mark (as a document in the genre of Gospel) needed to teach the resurrection (the other 3 did) and needed to have a version of the Great Commission, since the other Gospels did. Agenda? Pray tell, where is my agenda in these posts? I'm simply giving facts.
As for the "numerous endings" you referenced, this is not true. They are not numerous. Here they are:
1. There is the ending which stops at verse 8 leaves the apostles frightened and trembling: "And they went out quickly, and fled from the sepulchre; for they trembled and were amazed: neither said they any thing to any man; for they were afraid." This is not at all suitable for a Gospel ending, yet it is how Wallace thinks it should end.
2. There is an ending in very few mss which leaves Christ in the tomb.
3. There is what Metzger calls in his textual commentary the "traditional ending," and it also occurs in a slightly expanded version in only one Greek ms, Codex Washingtonianus.
Concerning the "traditional ending," Metzger says that it is "present in the vast number of witnesses" (A Textual Commentary on the Greek New Testament, 2nd ed., p. 103), and then he goes on to say, "The earliest patristic witnesses to part of all of the long ending are Irenaeus and the Diatessaron" (Ibid.). Irenaeus and Tatian (author of the Diatesseron) both lived in the 2nd century, which puts the longer ending attested extremely early, in fact, much earlier than the shorter ending, or the missing ending Wallace prefers.
Again, logic rules the day. The ending attested in the 2nd century and having "a vast number of witnesses" ought to have priority,
