I don’t disagree with the Catholic Catechism or the Catholic Faith that has been taught by Jesus Christ and His Catholic Church.
You can cite the Catechism and Church Fathers, but not produce any cogent thought and understanding.
At least I am not the one who is gonna have to answer the question:
What part of - "On the rock of this faith confessed by St. Peter, Christ built his Church." - do you fail to understand.
