Pastor "tries on" atheism for a year, is promptly fired by his Christian employers.

In the article of the OP, the guy actually links to that former pastor's blog where he details his... experience:

And he says:

So, I’m making it official and embarking on a new journey. I will “try on” atheism for a year. For the next 12 months I will live as if there is no God. I will not pray, read the Bible for inspiration, refer to God as the cause of things or hope that God might intervene and change my own or someone else’s circumstances. (I trust that if there really is a God that God will not be too flummoxed by my foolish experiment and allow others to suffer as a result).

I will read atheist “sacred texts” — from Hobbes and Spinoza to Russell and Nietzsche to the trinity of New Atheists, Hitchens, Dawkins and Dennett. I will explore the various ways of being atheist, from naturalism (Voltaire, Dewey, et al) to the new ‘religious atheists’ (Alain de Botton and Ronald Dworkin). I will also attempt to speak to as many actual atheists as possible — scholars, writers and ordinary unbelievers — to learn how they have come to their non-faith and what it means to them. I will visit atheist gatherings and try it on.

In short, I will do whatever I can to enter the world of atheism and live, for a year, as an atheist. It’s important to make the distinction that I am not an atheist. At least not yet. I am not sure what I am. That’s part of what this year is about.
