Can you imagine 1266 AD writing with ink and quill or what not and not having the luxury of making a mistake?
The 1st proof of God is seen as flawed: the infinite causal stair (effect and cause). I blelieve the church acknowledges it as being the one flaw of this genius's work.
This is known from my philosophy class and from it being common knowledge I assume.
The other 4 proofs are relatively secure I believe, I just received a summary of them, more of a lesson then a discussion from my uncle. Guy is a genius. Mentioned Kant and he went into existentialism and from a long list of names in the movement came upon "the greatest existential author, Thomas Aquinas". He's pure reason though part of his lesson is for me to read Aquinas's 5 proofs then connect it to a 1000 page philosophy book of summaries I presume then to read Hawking and how his greatest achievement was discovering "time has a beginning".
In regards to your last question no person exists. I simply thought the text said something it didn't. Aquinas simply referred to the earth being round as a well known fact derived from astronomers by mathematics and physicists by the matter itself and he was saying that you can have more than one way to prove something.
And the church was never against a round earth obviously just a heliocentric model.
