My points were not really an argument, they were really more of a general question. The Catholic faith was essentially the only Christian faith for over 1500 years, and even after the Protestant revolt the Christian world remained heavily Catholic for many years–the vast majority of the history of the Christian faith has seen the Roman Catholic faith as its center as given by the head of the Church, Jesus Christ.
Now. either the Catholic faith is the full faith, or it is not. If it is the full faith, and if Jesus did give us that full faith, then every person on earth (including the continuing revolters known as Protestants) should be Catholic.
If everyone should be Catholic, then how are we helping that scenario by basically saying Protestants and other people of other faiths hold the truth(s) as well? I know the Catechism, I also know that the Church does not equate the religions…yet the net impact of what the Church currently teaches is that many people walk away feeling as if all faiths hold divine truths that can save and that all faiths are more or less equal to each other (example: scientology is more or less equal to the Roman Catholic faith).
I think it is important to recall that the current statements by the Church in the Catechism has NOT always been the spoken teaching of the Church…one can wonder why suddenly all other faiths have been elevated, or the Catholic faith has been lowered.
That is a very real problem with the notion of ever hoping for unity.
