You can post taint so till the cows come home, the long ending by Mark is considered by the majority of scholars to be questionable.
Here is a typical internet source response:
Eusebius, an early church father, quoted a statement regarding the Gospel of Mark's ending, specifically mentioning "the accurate copies". He noted that in these copies, the Gospel concluded with Mark 16:8, where the women were afraid, and not with the longer ending (Mark 16:9-20).
Elaboration:
Eusebius's quote is relevant to textual criticism of the New Testament, particularly concerning the varying endings of the Gospel of Mark. He observed that some manuscripts ended at verse 8, while others included verses 9-20. He used the term "accurate copies" to refer to the manuscripts ending at verse 8, suggesting that these were the most reliable and authentic versions.
Why this quote is significant:
- Textual Criticism:
Eusebius's observation highlights the existence of different versions of the Gospel of Mark in antiquity, which is a key point in textual criticism.
- Influence of the Longer Ending:
The quote suggests that the longer ending (Mark 16:9-20) was not present in the earliest and most authoritative copies.
Early Church Understanding:
It provides insight into how the early church viewed the text of Mark and its various endings.
