Each and every saint that we commemorate is an example that His Light can shine through us. When we celebrate them, we celebrate Him first and foremost. But that doesn't fit the interpretation of others and so they accuse us of blasphemy.
I contend that there is no blasphemy in our hearts, our minds, or our practices.
And that is my point.
And not just saints as persons, but their relics and icons and the like.
