How did the First Vatican Council affirm the relationship between faith and reason?

The First Vatican Council, which took place from 1869 to 1870, emphasized the compatibility and mutual reinforcement of faith and reason. The council declared that both are vital for understanding truth and developing a robust theological framework. This perspective acknowledges that faith does not negate reason; rather, they complement each other.

The teachings from the council insisted that reason plays an important role in coming to know God and understanding divine revelation. By asserting that faith and reason are harmonious, the council provided a foundation for a rational approach to theology, encouraging engagement with philosophical inquiry and scientific discovery in a way that respects religious belief. This understanding is crucial in fostering a dialogue between faith communities and the secular world, affirming that true faith is not irrational but can be supported and enhanced by rational thought.
