Shroud of Turin evidence

I think Fr. Jonathan does a good job representing the Church on foxnews, where he is a regular contributor, but at least in this interview, I get confused when he says he has faith in the shroud, but that the shroud is not an element of faith. I know exactly what he means, but in a forum like foxnews, it is important to do our best to distinguish between private revelations and private faith versus the corporate faith of the Church in the original deposit of faith. I wouldn't be that good of doing it on tv in a short amount of time, but this interview is a little confusing for a marginal Catholic or a non-Catholic.
