Yes indeed, the church will fade away when Christ comes again. Last time I checked, friend, that hasn’t happened yet! – Father Barron
(Here’s his comment in its original context.) My response to him was “You should check again.”
In the meantime, let the significance of what the good father has acknowledged sink in. He is admitting that the place of the church gives way to the Christ who comes.
You can thus understand why the church does not want to say along with John the Baptist, “He must increase, but I must decrease.” (John 3:30)
Instead, the church (i.e. all of them – Roman Catholic, Eastern Orthodox, and Protestant) says along with the Pharisees, “This is the heir; come, let us kil him and seize his inheritance.” (Matthew 21:38).
