The Gospel of Mark for Separation from Judaism
The Gospel of Mark is the earliest one among the three synoptic gospels of Mark, Luke and Mathew.
Till the Gospel of Mark was issued, there had been no documents written by followers of Christ Jesus. It was, most probably, because writing books unique to Christ Jesus meant an expression of intention to separate from Judaism. Indeed, if followers of Christ Jesus had wanted to stay within the scope of Judaism, they should not have needed new documents.
But, the Gospel of Mark was written in Greek. This Gospel was not intended to be solely read by Hebrews or Israelites.
The Apostles and other early followers of Christ Jesus who lived in Jerusalem before the First Jewish–Roman War (66–73 CE) must have had no intention to quit being Judaists. They never thought that they had become something different from Judaists only because they believed in Christ Jesus. They didn't need any other books but conventional books such as the Torah or the Old Testament. What the Apostles read was not the New Testament but only the Torah and old Hebrew books.
So, while the Apostles lived, no new books concerning Christ Jesus were written and issued due to respect for them. Conversely, writing and issuing new books concerning Christ Jesus meant clear separation from Judaism. So, the Gospel of Mark was written in Greek, targeting Roman citizens and other gentiles who spoke Greek.
Especially, if the Gospel of Mark had not been written and issued, the Gospels of Luke and Mathew should not have been able to be written. Then, a new religion, Christianity, should not have been possible. In fact, 93% of contents of the Gospel of Mark were adopted in the two succeeding Gospels. And roughly speaking, a half of contents of each of Luke and Mathew is unique to itself. So, it is apparent that Luke and Mathew read the Gospel of Mark and decided to write their versions of Gospel, collecting information about the preaching of Christ Jesus that had been delivered decades ago.
Establishment of Christianity and its separation from Judaism started with the appearance of the Gospel of Mark. And "Mark" intended, from the beginning, to spread Christianity to Roman citizens and other gentiles by writing the book in Greek. It was "Mark" that decided to make Christianity separate from Judaism. So, "Mark" was the true founder of Christianity. But, it must be Christ Jesus that founded Christianity. It means that "Mark" was Christ Jesus. Christ Jesus must have continued to live after resurrection under the name of Mark.
Of cause, Paul played a key role in establishing early Christianity. But without the Gospel of Mark, documents written by Paul had less significance. Those documents would lose meaning. Readers of Paul's letters would not be able to understand what St. Paul was arguing and mentioning without the Gospels.
Therefore, Christianity was launched with the Gospel of Mark that was written and issued after all the Apostles and other early followers of Christ Jesus who had directly seen Christ Jesus preaching died and disappeared without their successors, namely Hebrew Christians.
So logically, it is quite reasonable to regard Mark who wrote the Gospel of Mark as Christ Jesus.
Traditionally Mark is thought to have been founder and bishop of the church of Alexandria, Egypt, where he was martyred.
