I commented on rationalism which is the product of the "rational" approach to Christianity that was proffered. The product of logic is scholasticism which reached its apex in St. Thomas Aquinas. Logic as St. Thomas demonstrated, proves Catholic doctrine.
"Reason is used in theology not to prove the truths of faith, which are accepted on the authority of God, but to defend, explain, and develop the doctrines revealed." - St. Thomas Aquinas, Summa Theologica, Answer 8.
Peace be with you
No. The product of logic is truth.
"Logic as St. Thomas demonstrated, proves Catholic doctrine."
No. Here's an example. Ezekiel 18 contradicts the Council of Orange's declaration of the doctrine of Original Sin. Contradictions render hypothesis false.
