Topic 25: Christian Life: Law and Conscience
Eternal law, natural law, the New Law or Law of Christ, human political and ecclesiastical laws are all moral laws in a very different sense, although they all have something in common. To form an upright conscience it is necessary to instruct the intelligence in the knowledge of the truth – for which we can rely on the help of the Magisterium of the Church – and to educate the will and emotions through the practice of the virtues.
Topic 32: The Sixth Commandment
Sexuality reaches the deepest core of the human person. True education in chastity is not satisfied with simply informing about the biological aspects, but helps people to reflect on the personal and moral values that come into play in our affective relationships with others. Sins against the sixth commandment are often a substitute for the lack of true love for which the heart yearns.
Topic 29: The Third Commandment
All men and women are called to participate in God’s creative power by perfecting the world through their work. They should also cease working on the seventh day, to dedicate it to divine worship and rest. Sunday is sanctified primarily by participating in Holy Mass. The Church establishes this obligation so that her children do not lack the essential nourishment they need to live as children of God.
Topic 31: The Fifth Commandment
No one, under any circumstance, can claim the right to directly kill an innocent human being. The fifth commandment also forbids striking, wounding or doing any unjust bodily harm to oneself or to one’s neighbours, as well as offending them with insulting words or wishing them harm. As regards abortion and euthanasia, respect for life should be a boundary line that no individual or state can violate.
Topic 33: The Seventh and Eighth Commandments
Christian life strives to order the goods of this world to God and to fraternal charity. Both temperance, to moderate their use and possession, and justice, to respect the rights of our neighbour, are important. Solidarity should be added to these two virtues. The eighth commandment forbids the misrepresentation of the truth in one’s relations with one’s neighbour. Christians have the duty to bear witness to the Truth who is Christ and to acknowledge Him before men.
Topic 20: The Sacraments
The sacraments are efficacious signs of grace. Sanctifying grace is a stable and supernatural disposition that perfects the soul to make it capable of living with God. The seven sacraments correspond to all the stages and important moments of each Christian’s life: the sacraments give birth and increase, healing and mission to the Christian's life of faith. They form an ordered whole, in which the Eucharist is at the centre, since it contains the Author of the sacraments.
Topic 19: The Resurrection of the Body
The resurrected body will be real and material, but not earthly and mortal. The enigma of death can only be understood in the light of Christ’s resurrection and our own resurrection in Him. Eternal life is what gives ultimate and permanent meaning to human life, to ethical commitment, to generous dedication, to self-sacrificing service, to the effort to communicate Christ’s doctrine and love to all souls.
Topic 17: The Church and the World
The Church is inseparably both human and divine. It lives and acts in the world, but its goal and strength are not here on earth but in heaven. The Church seeks only the salvation of mankind, but she is also concerned with temporal affairs. Each Christian faithful participates in the mission of the Church according to his or her condition and vocation, and the gifts received.
Topic 16: The Hierarchical Constitution of the Church
The Church is a structured society where some have the mission to guide others. The assistance of the Holy Spirit to the whole Church so that it may not err in believing is also given to the magisterium so that it may faithfully and authentically teach the Word of God. The Church has always called only baptised men to the order of the priesthood; she has felt bound by the will of Christ, who chose only men as Apostles.
Topic 15: The Church Founded by Christ
Throughout his life, Christ made clear what his Church would be like. The Church is the community of all those who have received the regenerating grace of the Spirit by which they become children of God. All the baptised share in the common priesthood; they are called to bring men and women into a relationship with God. The ecumenical movement is an ecclesial goal that seeks visible unity among Christians in the one Church founded by Christ.
