What Catholics Actually Believe

Constantine did not create the Catholic Church. He legalized Christianity in AD 313 through the Edict of Milan, ending persecution. The Church already existed for nearly three centuries before Constantine, with its own bishops, sacraments, Scripture, and creed.

What Catholics Actually Believe

The Catholic Church did not create the Bible — but it did recognize, preserve, and transmit it. The books of the New Testament were written by Apostles and their companions. The Church, guided by the Holy Spirit, discerned which writings were authentically apostolic.

What Catholics Actually Believe

Catholics did not add books — they preserved the original Christian Old Testament. The seven deuterocanonical books (Tobit, Judith, 1–2 Maccabees, Wisdom, Sirach, Baruch) were part of the Septuagint, the Greek Old Testament used by Jesus, the Apostles, and the early Church. Luther removed them in the 16th century.

What Catholics Actually Believe

Mary is called the Mother of God (Theotokos — 'God-bearer') because she is the mother of Jesus, who is God. To deny this title is to imply that Jesus is not truly God, or that Mary gave birth only to his human nature — a heresy condemned at the Council of Ephesus in 431.

What Catholics Actually Believe

No. Catholics venerate Mary — they honor her as the greatest of the saints and ask for her intercession. Worship (latria) is given to God alone. Veneration of Mary (hyperdulia) and the saints (dulia) is a distinct and lesser honor, as clearly defined in Catholic theology.

What Catholics Actually Believe

Yes. Jesus appointed Peter as the head of his Church, gave the Apostles authority to teach, baptize, forgive sins, and celebrate the Eucharist. The Catholic Church is the direct institutional continuation of that apostolic community.

What Catholics Actually Believe

Yes. Apostolic succession means that every Catholic bishop can trace his ordination back through an unbroken chain of bishops to the Apostles. This is not merely a legal claim — it is the means by which the authority and teaching of the Apostles is transmitted through time.

What Catholics Actually Believe

Because Christ gave the Apostles — and through them, their successors — the authority to forgive sins. The priest does not forgive sins by his own power; he acts as the instrument of Christ's forgiveness. Confession is not a barrier between the soul and God — it is the sacramental means through which Christ's forgiveness is made certain.
