One may or may not appreciate the religious aspect, but the Vatican has always been a hub for “refined thinkers.” And when it comes to establishing an (initial) point of discussion on such an ethically significant topic, I believe that the amount of thought distilled into this page has been considerable.
The Jesuit order - to which Pope Francis belonged (belongs?) - has a long and notable history of contributing to science and scientific discovery. So they are not just thinkers, but doers.
