When considering questions of the infinite, it takes a considerable lack of humility to assume there is no more to learn, IMHO
BTW, check Kurt Godel re: 2+2=4
The Catholic faith is a revealed religion. We know God by how He has revealed Himself to us, most completely in the person of Jesus Christ. We believe what God has revealed about Himself, because being God, He can neither deceive nor be deceived. The Church guards this deposit of faith as it was given by Our Lord Jesus Christ. The Church can neither add to it, nor subtract from it for that would take "a considerable lack of humility" to profess anything other than what God has revealed about Himself.
The Church cannot profess anything about God that He has not revealed about Himself, nor can it accept anything contrary to what has been revealed by God to be true.
