Napsal(a) Rev. George McCurdy and Rev. Martin Pennington
In this chapter, the organized church was increasing from external things to more external things. The course of its actions could lead but to one thing: corruption and breaches that would end with the destruction of internal or inmost things. Their decisions were against God and doctrine. The church with all things belonging to it would “perish.”
The symbolic meaning of "seeing" is "understanding," which is obvious enough that it has become part of common language (think about it; you might see what we mean). So when the Bible talks about seeing, the reference is to recognizing and understanding the truth intellectually.
