Well if I had billions of dollars worth of art
I might consider selling some
Because the concept of holding it in trust so that non-billionaires will have a chance to see it is foreign to you.
How do the poor benefit if the art vanishes into the private collections of narco traffickers and St. Peter’s is converted to a nightclub?
But this art is not the Vatican's as if it were a private or even a corporate asset. It is a kind of fiduciary trust. It is the physical and cultural patrimony of the Church. Which is to say, us.
And not only of "us" here now, but of generations of Christians to come--- if the Lord tarries.
