"Watered-down Christianity" = Protestantism, no requirements at all, none.
However, that doesn't sound very nice. I know Protestants who are charitable, good, worthy followers of Christ and they go to Church every Sunday, no excuses. They aren't "watered down" at all according to their own Protestant lights.

God puts the same requirements on all Christians, there are no special rules just for some of us.
