The quote is taking something that can be questioned (the angels existence) and showing it in something that can be done for sure (the act of painting it)

First off, this isn't really a yes or no question, this is an opinion.
My opinion is that photos that have been altered in any way should be marked. These days you never know what a person will do to say, get a job, advance a political agenda, or ruin the reputation of another person. The public has the right to the truth. Therefore, altered pictures should be marked or labeled in a way that differentiates them from others.
