Prove this assertion please.
I already did. Read it again. The condition of the world does not depend upon the condition of the Church. By saying that, you heap responsibility for the world's problems on God since you're essentially declaring that, as head of the Catholic Church, the Holy Spirit needs to be doing a better job in guiding the Magisterium. That's blasphemy.
If you believed that the Holy Spirit had guided the Magisterium effectively, you would accept Vatican II and the novus ordo. You don't, therefore, you cast guilt upon the Holy Spirit.
