So then you are no longer strangers and sojourners, but you are fellow citizens with the saints and members of the household of God, built upon the foundation of the apostles and prophets, Christ Jesus himself being the cornerstone.
The Church cannot make up new revelation as she pleases. She must guard faithfully what has been entrusted to her by the apostles. With their death, all public revelation ended till the Second Coming. So the Church is bound, by her nature to be apostolic. But to be apostolic is not merely to be conservative. It is also to be creative. For the Christ whom the apostle proclaim is creative and we are to be like him. But “creativity” is not just a synonym for “novelty” any more than “orthodox” is a synonym for “conservative.” The truly orthodox are, like St. Thomas or John Paul II, profoundly creative minds. That is why the apostolic faith is the living faith of the dead and not the dead faith of the living nor the thrill-seeking faithlessness of the living dead.
