How Teaching Developed

The Church establishes that salvation is open to all peoples, not only Jews. The New Testament canon begins to take shape.

Early Christians believed in the Real Presence of Christ in the Eucharist, baptismal regeneration, and the authority of the Apostles.

The Church grows under Roman persecution. The great Church Fathers write in defense of the faith. Martyrs witness to Christ with their blood.

Constantine ends persecution. The great ecumenical councils define the nature of Christ. Augustine shapes Western theology for a millennium.

Monasticism preserves civilization. The great cathedrals rise. Scholasticism reaches its summit in Thomas Aquinas. The Church shapes European culture.

Internal corruption leads to calls for reform. Luther, Calvin, and others break from Rome. The Council of Trent clarifies and renews Catholic teaching.

The Jesuits evangelize Asia, Africa, and the Americas. Baroque art glorifies God. The Church navigates the Age of Reason.

The Church defines papal infallibility, responds to modernity, and convenes Vatican II. John Paul II and Benedict XVI shape a new evangelization.
