From where did you get what I bolded?Second "Mark"
Source: Eusebius referring to Clement
Date: Eusebius c. 324, Clement c. 200
Description: Follower of Peter but not the Cephas (Peter) that Paul knew.
The whole thing about "Mark" the author of the gospel started with Papias (110-140), quoted by Eusebius:
"Mark, having become the interpreter of Peter, wrote down accurately, though not indeed in order, whatsoever he remembered of the things done or said by Christ. For he neither heard the Lord nor followed him, but afterward, as I said, he followed Peter, who adapted his teaching to the needs of his hearers, but with no intention of giving a connected account of the Lord's discourses, so that Mark committed no error while he thus wrote some things as he remembered them. For he was careful of one thing, not to omit any of the things which he had heard, and not to state any of them falsely."
Cordially, Bernard
