If you do a search in Bing Images for "Pius XII handshake", you will find similar handshakes, and yet how many traditionlists would call Pius XII a Freemason? Well, I for one could believe it, however, so what? We don't need (to go out of our way to) prove that B16 is a Freemason, to show people, that he is a punishment from God upon those that have itchy ears, which is all that he and all the progressivists are.
3 For there shall be a time, when they will not endure sound doctrine; but, according to their own desires, they will heap to themselves teachers, having itching ears:4 And will indeed turn away their hearing from the truth, but will be turned unto fables (2 Timothy 4:2-4)
