The Catholic Church is one of the oldest Christian Religion in the world. But the main question is who built the Catholic Church? Many protestants argue with this because it is not written in the bible. The Catholic Church was built by our Lord Jesus Christ upon the first Pope, Saint Peter the Apostle in 33 A.D (Matthew 16:18). After the resurrection and ascension of our Lord, the first ministry of Saint Peter and the other apostles has started (Acts 2:1-31).
