Virtually any question about the interpretation of Scripture or Christian doctrine is going to have numerous possible answers, depending on the tradition / perspective of the person answering. There are two ways to deal with this in the question itself, and the style of the answer depends (to some degree) on which angle the OP takes in asking the question.
Form A: Specify desired tradition / perspective
The question can be asked in the form, "From a [Roman Catholic] perspective, what is the significance of communion?"
The only correct way to answer a question of this form is to answer from the perspective specified by the OP.
Form B: Ask the question generically
We see these questions a lot. For example, "Can I believe in evolution and still be a Christian?".
Clearly the answer will depend on the perspective of the person answering.
The labeled answer: In some cases it makes sense to say "From a [Roman Catholic] perspective, [yes]."
The unlabeled answer: In other cases, attempting to describe your perspective with a label is less effective than simply describing your perspective by answering. (Some perspectives do not have a label. In many other cases, the label would appear as complete gibberish given its extremely infrequent usage.)
The generic answer: Sometimes people will attempt to answer a generic question with a generic (or survey) answer. For example, to the question about evolution and Christianity, one may answer by saying: "Some would say 'yes'. Some would say 'no'. Some would say 'maybe'."
It is important to remember that the vote is there to indicate whether or not the answer is helpful - not that it is correct, not that you like it, not that you agree, etc. For many questions, it is helpful to understand multiple perspectives. As a result, the voter is encouraged to up-vote all answers which would be helpful to future seekers.
In fact, folks will sometimes answer by describing a perspective they disagree with in order to provide another helpful perspective for the seeker to consider! (For example, see the quote and comments in this answer.)
Helpfulness depends entirely on the question:
For answers to questions of "Form A", the only helpful answers would be those which accurately represent the designated perspective
For "labeled answers" to questions of "Form B", the only helpful answers would be those which accurately represent the label
For "unlabeled answers" to questions of "Form B", a helpful answer would be one which the voter finds helpful in understanding the topic more fully
For "generic answers" to questions of "Form B", a helpful answer would be one which does a good job representing each of the perspectives listed.
There is a real challenge in providing a survey answer in response to a generic question. Consider the following scenario.
Question: How should Genesis 1 be understood?
Answer 1: It should be understood literally; God really did make everything in 6 (24 hour) days, (proceeds to make a strong case for this view)
Answer 2: It should be understood literally; God made everything in 6 long periods of time, (proceeds to make a strong case for this view)
Answer 3: Genesis 1 is intended to show that God made everything, but it is not a science book, so it should not be read as such, (proceeds to make a strong case for this view)
Answer 4: Genesis is more of a story with a lesson than a history book, (proceeds to make a strong case for this view)
Answer 5: Some people say [...], some people say [...], some people say [...], some people say [...], some people say [...], (proceeds to provide a brief summary of each view)
In this case I would not expect Answer 5 to be very "helpful". For one thing, it is already apparent to everyone that there are different perspectives. Once that is established, Answer 5 is not very "helpful" at all - no "strong case" is made for anything, and the reader does not really walk away having learned anything new.
At times a survey answer is the most helpful answer, but it is difficult to compete with more comprehensive answers which often come directly from the people who believe and understand their perspective, and can make a strong case for it.
