Recently an answer was edited with only a revision history of "per https://hermeneutics.meta.stackexchange.com/a/777/208". The link is to the top-voted answer to What kind of site do we ultimately want to have? The revision replaced:
The mystery not yet revealed in this passage, though, is that because Christ will mediate in all three roles, those who were wicked will be righteous, and they will stand with him in his offices.
In my opinion, these edits violate the guidelines for editing:
Respect the author's voice and content. This is partly covered in the top point, but I'll be a bit more explicit about certain points here. People may write as they wish to write - while as a site we focus on content, as a community there are people behind every post. People usually do not like to speak in a voice that is not theirs. So as long as it isn't actively interfering with the goal of the post, there isn't a need to change things.
An edit better fitting the guideline would have been to insert "Christians believe..." rather than remove the beliefs that the editor disagrees with.
