I remember about 30 years ago there was a “man on the street” poll taken on this and I remember one woman’s response: “Of course I’m a Christian. I’m an american, aren’t I?”
That is, there may be an increase in ACTUAL Christians while, at the same time, there is a decrease in those that claim to be.
“...ACTUAL Christians ... those that claim to be...”
Please, what is the difference and should a different word be used for one of the groups?
