God's Word is given to the People of God, who are found within the confines of the Catholic Church. The Catholic Church comprises all those churches throughout the world which are in union with the Roman Church. It has been so since the time of the Apostles. The Church has grown larger and she has also grown up. Just because the people are no longer meeting in secret in private homes doesn't make the Church any less THE Church.
The Church doesn't do everything the way it used to BECAUSE it has grown into a connected body of over 1 billion (putative) members. It's like a seed that was planted and then actually GREW. It doesn't look like a seed anymore, if it did then it would be a colossal failure.
It may well happen that the institutional structures of the Church will collapse globally due to the insanity of the present synod (or sin nod, as the case seems to be shaping up). Whole churches, (aka dioceses) and even entire nations, could fall into apostasy, but the Church will still be the People of God united in belief and practice with the Roman Church.
What it will assuredly NOT be is some group of people who set themselves up in opposition to the true Church, slap a spire on their building and call themselves Mount Holy Olive Second Baptist Zion Church of God in Christ of Resurrected Latter-Days AME or what have you.
The love just glistens!
