“The Council teaches that ‘the obediance of faith must be given to God who reveals himself.’ This brief but dense statement points to a fundamental truth of Christianity. Faith is said first to be an obediant response to God.
This implies that God be acknowledged in his divinity, transcendence and supreme freedom. By the authority of his absolute transcendence, God who makes himself known is also the source of the credibility of what he reveals. By faith, men and women give their assent to this divine testimony.
This means that they acknowledge fully and integrally the truth of what is revealed because it is God himself who is the guarantor of that truth. They can make no claim upon this truth which comes to them as gift and which, set within the context of interpersonal communication, urges reason to be open to it and to embrace its profound meaning.
This is why the Church has always considered the act of entrusting oneself to God to be a moment of fundamental decision which engages the whole person. In that act, the intellect and will display their spiritual nature, enabling the subject to act in a way which realizes personal freedom to the full.”
“It is faith that allows individuals to give consummate expression to their own freedom. Put differently, freedom is not realized in decisions made against God. For how could it be an exercise of true freedom to refuse to be open to the very reality which enables our self-realization? Men and women can accomplish no more important act in their lives than the act of faith; it is here that freedom reaches the certainty of truth and chooses to live in that truth.”
