"Poor" has its meaning in relation to God, not in relation to "rich".
It means this: that state which allows for the greatest extent graces possible that God wishes to give, filled to the brim and shaken down. Gifts beyond our imagining. Christ Himself - the way, the truth and the life.
This is the poorness of the Church that is present in even the most ornate and rich liturgy.
The world has infested the Church together with the prince of the world, Satan. She has been robbed of her poverty. Her members are puffed up and stiff-necked and altogether on a lost path.
The TLM raises us to the angelic spheres does it? And apparently afterwards, if we were to take the example of certain people, it casts you into the hell-pits of bitterness, sarcasm and calumny towards a newly-elected Pope and the sowing of doubt and division and scandal in the minds of innumerable readers concerning the highest ecclisial members. Mortal sin?
