Yes.
Christ's. He founded the Catholic Church and promised us it is the foundation and pillar of truth.
Everyone else is just making stuff up to suit themselves.
I don’t remember Christ telling us to pray the rosary to Mary-either in the Protestant bible or the Catholic bible. But then, perhaps I need someone to interpret it for me?
That promise wasn't to you...We've read the scriptures...We're reading your catechism...We see your religion...
Your's is not the church of the scriptures...Jesus did not found your religion...That's abundantly clear...
That's why you have a catechism to follow...Because you can't follow the scriptures...
