And it's not even necessary for the debate to rest upon a single definition of the word. It's possible for both strands of the debate to revolve around entirely different concepts. Each opening statement frames a different discussion. Each rebuttal responds to the opening statement. And so forth.
Both sides must articulate how their idea of "faith" interacts in some non-trivial manner with the concept of "virtue." Without trying to over-anticipate the debate, if the atheist takes a very hard line like "Faith is belief with no evidence, and there's no virtue in that at all" then the atheist will have to hold that line the entire time. The rebuttal can (for example) point out that even "no-evidence faith" has led to people doing good things, which is still understood to be virtuous behavior (not a strong rebuttal, but good enough for the example). The atheist would then need to come back with something to rescue that, such as using some sort of "faith-in-itself is without virtue" position or trying to point to negative behavior as somehow "cancelling out" good behavior (neither position is very strong, imo). The point here is that since the atheist claims "no virtue at all" he needs to show that absolutely no good can come of faith (belief in something in the absence of evidence). That's just a really, really hard position to defend.
The end goal here is not a pursuit of "truth" per se. The goal is to put forth a better argument than the other side. You should think of each opening statement as claiming some "territory" on a battlefield. From there, each side attempts to "push back" against that advance. Whichever side ends up with the most territory wins. A very broad claim like the one above may take a huge amount of ground from the start, but it's easy to poke holes. A more conservative definition may be easier to defend, but with less initial ground taken, each loss hurts a lot more. This is why the opening statement is critical as it frames all of the responses that will follow. It's often the case that the one who frames the discussion better wins.
