25. How does man respond to God who reveals himself?
Sustained by divine grace, we respond to God with the obedience of faith, which
means the full surrender of ourselves to God and the acceptance of his truth
insofar as it is guaranteed by the One who is Truth itself.
26. Who are the principal witnesses of the obedience of faith in the Sacred
There are many such witnesses, two in particular: One is Abraham who when
put to the test “believed in God” (Romans 4:3) and always obeyed his call. For
this reason he is called “the Father of all who believe” (Romans 4:11-18). The
other is the Virgin Mary who, throughout her entire life, embodied in a
perfect way the obedience of faith: “Let it be done to me according to your
word” (Luke 1:38).
27. What does it mean in practice for a person to believe in God?
It means to adhere to God himself, entrusting oneself to him and giving assent
to all the truths which God has revealed because God is Truth. It means to
believe in one God in three Persons, Father, Son, and Holy Spirit.
28. What are the characteristics of faith?
Faith is the supernatural virtue which is necessary for salvation. It is
a free gift of God and is accessible to all who humbly seek it. The act
of faith is a human act, that is, an act of the intellect of a person -
prompted by the will moved by God - who freely assents to divine truth. Faith is also certain because it is founded on the Word of God; it works “through charity” (Galatians 5:6); and it continually grows through listening to the Word of God and through prayer. It is, even now, a foretaste of the joys of heaven.
29. Why is there no contradiction between faith and science?
Though faith is above reason, there can never be a contradiction between faith
and science because both originate in God. It is God himself who gives to us the
light both of reason and of faith.
“I believe, in order to understand; and I understand, the better to
believe.” (Saint Augustine)
