WE ALL know about people who profess to be Christians but act as if they don’t know the meaning of the word. Politicians are particularly good at this.
There is another side to this coin, but unfortunately these good people are less visible.
There are many version of Christianity and plenty of divergence in what it means to be a Christian.
In my time, I’ve known a couple of priests who were agnostic and at least one who was an atheist.
I also once met a nun in the Star Mountains who seemed unsure about her faith and the existence of a god.
