I agree with RomanTheo. There is visibility today in the material structures of the Church. But what is it that is visible? Nothing but heresy, blasphemy, impiety, sacrilege, destruction, sin, and scandal.
This is the visibility of iniquity; not holiness.
How do you know that there's no holiness at all in the visible and material structure of the church? The negative elements that you describe above do exist, but can you be quite sure that nothing of the Catholic Faith remains?
