'If everything is sacred, what is it being set apart from?' From our egos---which sees everything in a win/lose situation, in a competitive situation, in a us vs. them situation.

God's generous and gracious love and grace is everywhere, open to all.  But our egos, developed more by culture, rather than by the Gospel, see
distinctions everywhere.  The HOLY and God's presence is indeed everywhere---but this is invisible to those who are too engaged in their ego and not in gratitude to God for all of God's grace and love.
