"(A = A) if and only if (A ~= ~A)"
Obviously, Father Totti wasn't aware of many things including the simple concatenation of Albert Einstein's initials that returns another vowel, letter O -- a letter whose shape is very similar to the shape of the circle and number zero. But even if he were through rather difficult "God doesn't play dice with the universe," that wouldn't help him to modify GOD into G0D, which is an indispensable catalyst in forming the theory explaining the mysterious burning of the negation Venn diagram.
He didn't mention anything about Revelation 22:13 to Father Luciani. He had good reasons not to. Both priests occasionally discussed the paranormal event that took place in the monastery in a general manner, and, on one occasion, Father Totti instilled an idea in Father Luciani's mind while discussing a rather small number of official miracles of the 20th century. Father Totti pretentiously viewed this state as very positive: God is surely aware of the high degree of faith in Him and so there is no reason for Him to further support the belief in His existence by initiating multitude of plainly observable phenomena of a religious character. That pleased far less liberal Father Luciani who decided to make this a subject for his next essay. He couldn't finish his previous writing on theism and atheism due to the "advice" of bishop Cannavari who became intuitively protective and decided to draw a precautionary line between Father Luciano's activities and the mysterious burning of the copy of the Venn diagram.
Father Totti was more analytic in concluding that the mysterious burning of the Venn diagram could be somewhat connected with Father Luciani's essay for which he made a copy of the diagram. The diagram included variable A where the symbol '~' negated whatever value was assigned to A. Father Totti wasn't mentally blind though; he knew that given the circumstance, the "whatever value" could have been restricted to
Ateo
~Ateo
where ~Ateo didn't have any other option but to join the population of theists.
But unrelated coincidences do happen frequently and there were no other arguments in the plain view that would tie the knot between Father Luciani's essay and the mysterious burning, which turned also A and ~A into ashes. The idea that God tossed the match just to say that He disapproves the occasional bickering between theists and atheists -- an idea likely to be born in the head of a cardinal -- didn't even cross Father Totti's mind. God's mind could have worked "mysterious ways," but in Father Totti's eyes, the real God was an intelligent person.
But this all didn't concern the Heavens that much. The Heavens had a job to do. Namely, to create the circumstances under which Father Totti would be able to modify GOD into G0D in non-arbitrary way. The modification was particular in solving the mystery of the burning copy of the Venn diagram. The type of solution will satisfy to some extent Father Totti, but he will never know the true reason why the copy of the Venn diagram went up in smoke, coz the reason involved realities that were, are, and will remain unknown to mankind forever and ever. Actually there is nothing super mysterious in what the Heavens wanted to do. The turning of GOD into G0D and the following transformations of other related symbols involves a brain performance that the Heavens needed to monitor.
