Yes. The Catholic Church is the only Church which teaches all the truths that Jesus Christ taught. Many other Christian communities have rejected the Sacraments of Penance and Anointing of the Sick, the Mass and the Real Presence of Jesus in the Eucharist, the spiritual supremacy of Peter and his successors, the popes, the efficacy of grace, and man’s ability …

The Catholic Church is apostolic because it is able to trace its lineage in unbroken continuity back to the Apostles. Jesus said to Peter, “And I tell you, you are Peter, and on this rock I will build my church, and the powers of death shall not prevail against it” (Matthew 16:18). Speaking to all the Apostles, He said, “All …

When we say, “I believe in the Communion of Saints,” we mean that we believe that there is a union, a fellowship, of all souls in whom the Holy Spirit, the Spirit of Christ, dwells. This communion is the union of the members of the Church on earth, in Heaven, and in Purgatory. The word “communion” means “union with.” The …

The Church is called the Church Militant because it is the Church here on earth which is still fighting against sin and error.

We must have reverence toward the bodies of those who have gone before us in death, and we must pray for the souls of our deceased relatives and friends, and all of the faithful departed. We show respect for the bodies of the deceased because they were temples of the Holy Spirit and are destined to rise gloriously. We can …

The Catholic Church ministers extensively to the bodily needs of people by helping those in need, by seeking to relieve the causes of suffering, and by building up a better life for man. Its vast health care and social welfare systems are found throughout the world. Although the Church is deeply involved in ministering to the bodily needs of people, …

We can help unbelievers find God by the witness of our lives of firm faith in God and personal love of Christ, and by our goodness and love towards unbelievers. We can help people to turn to God if we give them a good example of our own deep faith in God. If people see our love for Christ in …
