Must the Church become more transparent?

Transparency is an important thing nowadays, if you want others to trust you. The Church has grown almost 2000 years in a world where people did not require transparency. They just trusted the Church.

But nobody is fully transparent. And transparency is not cheap, it causes considerable administrative effort. There is always a balance between what is useful and what is realistic. If you try to explain to everybody why you act as you act, you will never get your job done.
