Just a bit of sidebar here....I have often wondered why we don't look closer at the procession, which will be literal and visable, with Jesus Christ leading thousands upon thousands. What a spectical this will be as all eyes observe throughout the world...truly an astounding event!
To imagine 'heaven opens' is profound beyond measure...and The procession goes on for hours. Magnificent depiction of our conquering King and all the saints with Him ...
You just described the Mass.
