We should go back to the era when major monastic land holdings controlled a large percentage of arable land, and such monasteries owned the serfs that worked the land. All for the gory of God.
One doesn't have to become an extremist and go iconoclastic, but a health amount of skepticism about how money is being spent within the church is a good thing - even laying aside the issue of whether that many diamonds, that many gold leafed icons are really necessary, major financial scandals in multiple jurisdictions in the past few years ought to make the laity aware that no hierarch can have a carte blanche with our money.
"Have Aaron your brother brought to you from among the Israelites, along with his sons Nadab and Abihu, Eleazar and Ithamar, so they may serve me as priests. Make sacred garments for your brother Aaron, to give him dignity and honor. Tell all the skilled men to whom I have given wisdom in such matters that they are to make garments for Aaron, for his consecration, so he may serve me as priest. These are the garments they are to make: a breastpiece, an ephod, a robe, a woven tunic, a turban and a sash. They are to make these sacred garments for your brother Aaron and his sons, so they may serve me as priests. Have them use gold, and blue, purple and scarlet yarn, and fine linen.” Exodus 28:1-5
The rest of Chapter 28 in the book of Exodus goes on in fine detail how the finest linens and jewels were to be used for the priest’s vestments. This was done at a time when Israel was hardly a “rich” nation, and there were many poor among them.
Yes, we are to give to the poor, and minister to those in need. But at the same time our Temples are to be beautifully decorated, as are our priest’s garments.
