Evidence for inclusion of Mark 16:9-20
The patristic writings that indicate acceptance of the verses as genuine are remarkably extensive. From the second century, Irenaeus, who died c. A.D. 202, alludes to the verses in both Greek and Latin. His precise words in his Against Heresies were: “Also, towards the conclusion of his Gospel, Mark says: ‘So then, after the Lord Jesus had spoken to them, He was received up into heaven, and sitteth on the right hand of God” (3.10.5; Roberts and Donald¬son, 1973, 1:426). It is very likely that Justin Martyr was aware of the verses in the middle of the second century. At any rate, his disciple, Tatian, included the verses in his Greek Diatessaron (having come down to us in Arabic, Italian, and Old Dutch editions) c. A.D. 170.
Third century witnesses include Tertul¬lian, who died after A.D. 220, in his On the Resurrection of the Flesh (ch. 51; Roberts and Donaldson, 1973, 3:584), Against Praxeas (ch. 30; Roberts and Donaldson, 3:627), and A Treatise on the Soul (ch. 25; Roberts and Donaldson, 3:206). Cyprian, who died A.D. 258, alluded to verses 17-18 in his The Seventh Council of Carthage (Roberts and Donaldson, 1971, 5:569). Additional third century verification is seen in the apocryphal Gospel of Nicodemus. Verses 15-18 in Greek and verses 15-19 in Latin are quoted in Part I: The Acts of Pilate (ch. 14), and verse 16 in its Greek form is quoted in Part II: The Descent of Christ into Hell (ch. 2) (Roberts and Donaldson, 1970, 8:422,436,444-445). De Rebaptismate (A.D. 258) is also a witness to the verses. All seven of these second and third century witnesses precede the earliest existing Greek manuscripts that verify the genuineness of the verses. More to the point, they predate both Vati¬canus and Sinaiticus.
Fourth century witnesses to the existence of the verses include Aphraates (writing in A.D. 337—see Schaff and Wace, 1969, 13:153), with his citation of Mark 16:16-18 in “Of Faith” in his Demonstrations (1.17; Schaff and Wace, 13:351), in addition to the Apostolic Constitutions (5.3.14; 6.3.15; 8.1.1)—written no later than A.D. 380 (Roberts and Donaldson, 1970, 7:445,457,479). Ambrose, who died A.D. 397, quoted from the section in his On the Holy Spirit (2.13.145,151), On the Christian Faith (1.14.86 and 3.4.31), and Concerning Repentance (1.8.35; Schaff and Wace, 10:133,134,216,247,335). Didymus, who died A.D. 398, is also a witness to the genuineness of the verses (Aland, et al., 1983, p. 189), as is perhaps Asterius after 341.
Patristic writers from the fifth century that authenticate the verses include Jerome, noted above, who died A.D. 420, Leo (who died ! 461) in his Letters (9.2 and 120.2; Schaff and Wace, 1969, 12:8,88), and Chry¬sos¬tom (who died A.D. 407) in his Homilies on First Corinthians (38.5; Schaff, 1969, 12:229). Additional witnesses include Se¬veri¬an (after 408), Marcus-Eremita (after 430), Nestorius (after 451), and Augustine (after 455). These witnesses to the genuineness of Mark 16:9-20 from patristic writers is exceptional.
The evidence for inclusion that comes from the ancient versions is also diverse and weighty—entailing a wide spectrum of versions and geographical locations. Several Old Latin/Itala manuscripts contain it. Though Jerome repeated the view that the verses were absent in some Greek manuscripts—a circumstance used by those who support exclusion—he actually included them in his fourth century Latin Vulgate (and, as noted above, quoted verse 14 in his own writings). The verses are found in the Old Syriac (Curetonian) as well as the Peshitta and later Syriac (Palestinian and Harclean). The Coptic versions that have it are the Sahidic, Bohairic, and Fay¬yumic, ranging from the third to the sixth centuries. The Gothic version (fourth century) has verses 9-11. The verses are also found in the Armenian, Georgian, and Old Church Slavonic versions.

“Their argument, though, is further undercut by the fact that one of these two, Vaticanus, actually contains an entire blank column after v. 8 which is close to the right size to fit vv. 9-20, suggesting that the scribe who copied this manuscript was aware of the existence of this ending, and was unsure whether to omit the passage, so leaving a space should it need to be filled in later. It should also be noted that the four uncial manuscripts given above as containing the shorter, alternative ending after v. 20 each also refer to the longer ending by itself as an alternate reading, indicating some uncertainty on the part of their scribes”

“Irenaeus quotes Mark 16:19 outright14 (~177 AD), and Tatian the Assyrian included the ending in his Diatesseron15, a document attempting the harmonisation of the four Gospel narratives (~175 AD). Tertullian refers to Mark 16:19 around 215 AD16, and Tregelles reports17 that Hippolytus (~235 AD) quotes Mark 16:18-19 at least twice. In Cyprian’s account of the 7th Council of Carthage (256 AD), he records a strong allusion made by Vincentus of Thibarus to Mark 16:17-1818. The Apostolic Constitutions (3rd-4th c. AD) quote Mark 16:1619, as well as alluding to Mark 16:15 twice elsewhere. Macarius Magnes (~390 AD) reports that Mark 16:18 was an object of attack by the Neoplatonist Porphyry or his student Hierocles (whose works are generally dated about a century earlier), discussing both their objections to the message of the verse (but not its authenticity) and Macarius’ own defense of the same20. The Syrian patristic Aphraates (~345 AD) cites the ending as well21, showing that it was accepted within Syriac Christianity.”
