I would not dispute that a celebration like this is beautiful and awe inspiring, and I have no problem with occasionally participating in a service that reminds us of the important tradition of the Church. Also it would be wrong of me to suggest that people cannot be strengthened in their faith by these celebrations. But I have to ask people....where in the entire Bible do Jesus or any of his apostles indicate that is this how they wished their Church to behave. These services do not project the image of Christ. They project the image of a Church that lost its way somewhere in the Middle Ages when it was taken over by nobility and power and monarchy and tried to convince people that building and worshiping in huge cathedrals dripping with riches and opulence was somehow representative of the Jesus of the New Testament who told people to give up their riches and follow him.

1 Tim 6:6 "There is great gain in godliness with contentment; for we brought nothing into the world, and we cannot take anything out of the world; but if we have food and clothing, with these we shall be content." I think this is the Biblical ideal that underlines what you said about Justice sometimes(but not always) being a disguised search for power and wealth. Poverty in life can truly lead to humility, which is the basis for accepting God's mercy. I would suggest that perhaps the Church itself tries to practice what it preaches in that regard. I think the Lord would be somewhat happier with your teaching if you presented it surrounded by less opulence and wealth.
