I'm answering you here because I also want to say something of a practical nature. The rule here, for some reason I don't understand, is that you must always add your comments at the 'bottom of the page, not the top!
About Leonardo's religious views: This is a matter that is almost entirely open to speculation. In his journals he occasionally made severe criticism of the church as an organisation, and in particular, monastic life. Other than that, he was silent. We know practically nothing about Leonardo's personal feelings on any subject.
Vasari indicates that Leonardo may have been sceptical about religious matters for most of his life, because he says that Leonardo, on his death bed, sent for a priest and learnt about the Christian faith. He was give the sacrament before his death. That is all we know.
Michelangelo, on the other hand, was a biblical scholar. It is my bbelief that the scheme for the Sistine Chapel Ceiling is entirely Michelangelo's devising.
In the article on Leonardo, there is simply no room to go into speculative matters. The article is very long already. For that reason, there are three other articles: Leonardo da Vinci - scientist and inventor, Cultural depictions of Leonardo da Vinci and Leonardo da Vinci's personal life.
The place to include the various theories about his religious beliefs is on the latter page, along with the speculation about his sexually and so on.
I added a suggestion to split the article to 'Inventions, and
(social/political and) scientific inquiries (Benjamin Franklin)', perhaps giving 'social contributions and studies' its own article. Sidelight12 (talk) 15:37, 27 August 2012 (UTC)
