17. Jesus replied, “Blessed are you, Simon son of Jonah, for this was not revealed to you by flesh and blood, but by my Father in heaven.
14 What good is it, my brothers and sisters, if someone claims to have faith but has no deeds? Can such faith save them? 15 Suppose a brother or a sister is without clothes and daily food. 16 If one of you says to them, “Go in peace; keep warm and well fed,” but does nothing about their physical needs, what good is it? 17 In the same way, faith by itself, if it is not accompanied by action, is dead.
18 But someone will say, “You have faith; I have deeds.” Show me your faith without deeds, and I will show you my faith by my deeds. 19 You believe that there is one God. Good! Even the demons believe that—and shudder.
26 We begin our profession of faith by saying: “I believe” or “We believe.” Before expounding the Church’s faith, as confessed in the Creed, celebrated in the liturgy, and lived in observance of God’s commandments and in prayer, we must first ask what “to believe” means. Faith is man’s response to God, who reveals himself and gives himself to man, at the same time bringing man a superabundant light as he searches for the ultimate meaning of his life. Thus we shall consider first that search (Chapter One), then the divine Revelation by which God comes to meet man (Chapter Two), and finally the response of faith (Chapter Three).
