"Suppose" the "faithful servant or slave" does not preach Christ delay or gets drunk and parties. He beats his fellow servants with emotional black mail. Would the ending change. No
You can read that chapter many ways! The master could be YHWH and Jesus could be the servant. In my view point, the conversation is to prove that only Jesus was handed such a responsibility. Through only him holy spirit is given which is food.
Also, Jesus never answered the question. 41Peter said, "Lord, are You addressing this parable to us, or to everyone else as well?" Probably neither! Peter was just as puzzled with Jesus saying as we are today.
Kind of hard to emotionally black mail people over an unanswered question and a parable at that!
Many people try to make claim to that title with poor results! Unfortunately, it has harmed many for believing them.
Anyhow there are other ways to interrupt that chapter and reading it for yourselves is better than depending on a religion. What religion would not want that power!
Haha I like what DD said.
