Questions 121 to 128
This section talks about what the Church is and the role of the Church and its members.
See What does Church mean?
Go to Lumen GentIum (from Vatican II on the Church):
He [God] planned to assemble in the holy Church all those who would believe in Christ. Already from the beginning of the world the foreshadowing of the Church took place. It was prepared in a remarkable way throughout the history of the people of Israel and by means of the Old Covenant.(1*) In the present era of time the Church was constituted and, by the outpouring of the Spirit, was made manifest. At the end of time it will gloriously achieve completion, when, as is read in the Fathers, all the just, from Adam and “from Abel, the just one, to the last of the elect,”(2*) will be gathered together with the Father in the universal Church.
The essential nature and task of the Church:
… [T]he only truly independent mind … [is] the Church. And that keeping her company, entering into her, entrusting yourself to her faith–which is allegedly being nothing but infantile and dependent–represents in reality the greatest degree of independence from the spirit of the age and signifies greater boldness than is embodied in any other possible position. …That is not an infantile dependence; that is courage to contradict and the freedom to go against prevailing opinions, the freedom that offers us a firm footing and which the Church has not invented for herself.’ – Cardinal Ratzinger (Full text)
To gain a better understanding of this concept, read the comments section of this blog called Institution of the Catholic Church by Christ.
See Vatican II: the Church as the people of God.
Read the Encyclical on the Mystical Body of Christ:
13. If we would define and describe this true Church of Jesus Christ – which is the One, Holy, Catholic, Apostolic and Roman Church  – we shall find nothing more noble, more sublime, or more divine than the expression “the Mystical Body of Christ” – an expression which springs from and is, as it were, the fair flowering of the repeated teaching of the Sacred Scriptures and the Holy Fathers.

Questions 3 to 6
This chapter of the YOUCAT: Man Is Receptive to God, draws heavily on an understanding of the metaphysical, which in layman’s terms is; what is not physical, what is invisible or the spiritual element of existence.
Joel Hodge writes about our yearning for God in an article called The value of theology and the mystery of life;
What Christian faith involves is completely natural to human living: we place our faith in an Other who shows us what it means to be human by his living. We all do this in some form. Christianity is explicit about it, so much so that we devote an academic discipline – theology – to the rational study and explication of our faith. This is, in part, why theology is ‘queen of the sciences’ as it is concerned with the most important and fundamental human questions and experiences. It is the love of God in Jesus that has also allowed Christians to know their lives better, and so flourish in terms of art, music, knowledge, and so on. In this regard, the works of Rodney Stark and René Girard, amongst others, have shown how Christianity has revolutionised human thought and culture.
Moving on to human reason;
The most regarded document on the link between faith and reason is Fides et Ratio by Bl. Pope John Paul II:
Faith and reason are like two wings on which the human spirit rises to the contemplation of truth; and God has placed in the human heart a desire to know the truth—in a word, to know himself—so that, by knowing and loving God, men and women may also come to the fullness of truth about themselves (cf. Ex 33:18; Ps 27:8-9; 63:2-3; Jn 14:8; 1 Jn 3:2).
In reading this text we begin to see just how important a solid grounding in the field of philosophy is to fully appreciate our faith and to be able to have meaningful dialogue with others about what we believe and, moreover, to understand the principles of theology.
Indeed, if you have ever had dialect with a non-believer, you would have an insight into this question and just how important a knowledge of philosophy, and consequentially, the appeal to human reason is.
If for instance, every day we struggle with wanting to do our own thing and especially if in the past you have had a lapse of faith or weren’t a religious person, you will know how easily we can convince ourselves that because it is hard to live a life close to God, such a life would limit our freedom and therefore must be wrong. In reality though, only a life in Christ guarantees our freedom.
The Pope’s Message for 2011 World Youth Day does a lot to explain this;
Dear friends, the Cross often frightens us because it seems to be a denial of life. In fact, the opposite is true! It is God’s “yes” to mankind, the supreme expression of his love and the source from which eternal life flows. Indeed, it is from Jesus’ heart, pierced on the Cross, that this divine life streamed forth, ever accessible to those who raise their eyes towards the Crucified One. I can only urge you, then, to embrace the Cross of Jesus, the sign of God’s love, as the source of new life. Apart from Jesus Christ risen from the dead, there can be no salvation! He alone can free the world from evil and bring about the growth of the Kingdom of justice, peace and love to which we all aspire.
However, as he points out in this article, we must remember that ‘[i]t is better to be a searching agnostic than a false believer.’
Yes, we must tell others about our faith!
It is our responsibility to engage with non-believers firstly by appealing to their faculty of reason, vouching for the existence of God and the truth of His Church.
How do we do this seemingly impossible task? Firstly we must remember that when a person outrightly denies or is ambivalent about the existence of God, as the question says, they hope deep down that beyond this life they cannot have come from nothing and go back to nothing. This gives us the confidence to undertake this task, but also, we must remember the value of prayer and the gifts of the Holy Spirit that we have been given, especially in the Sacraments of Baptism and Confirmation – These inspire us to do what is right.
Here is a website on evangelization called Ask a Catholic a Question which has some helpful advice.
Lastly, as Archbishop Chaput said, ‘teaching the truth should always be done with patience and compassion, as well as firmness.’
