“152. Which is the one true Church established by Christ?
The one true Church established by Christ is the Catholic Church.”
Yes. And that church is universal; composed of every believer everywhere. Within it are denominations” or sects. One of these is Roman Catholicism. It is hubris and sheer madness to suggest that Roman Catholicism alone represents the height, breadth, and depth of Christ’s universal, invisible body.
