Always reforming

Alistair McGrath is a Christian British professor and author of a lot of good books (I've read some).  One is "Christianity's Dangerous Idea."

He says that the dangerous idea is the very foundation of Protestantism:  from the start and right up until now, that idea is that every Christian has the right to interpret scripture according to his own conscience.

Especially my Catholic friends will immediately see the inherent danger, which is instability.  But there's also inherent advantages of dynamism.

"There are dangers to the subjectiveness that comes with this form of religion, but, McGrath suggests, there are advantages as well. Protestant movements that are perpetually changing are usually also perpetually re-examining themselves, asking, “Could we do this better?” The principle of semper reformanda (always reforming) applies just as much now as it did in Luther’s day."  (from breakpoint.org)
