I didn't know that!
Here is the part of him being a minister:
Newdow says his pledge fight -- unlike AU's strategic battles -- is essentially personal. The act of 1954 infringes on his own religious freedom, he claims. He's a minister of atheism, ordained by the Universal Life Church, a controversial California entity that has ordained millions of ministers of all stripes and beliefs at the mere asking. Newdow says he'll be opening his church, the First Amendment Church of True Science (FACTS), soon, likely on the Internet. Atheists, he argues, shouldn't have to pledge to a God in whom they don't believe. He compares his refusal to that expected of Christians, who would surely refuse to pledge allegiance to "one nation under Allah." Atheists, he says, are among the last groups in the U.S. that are fair game for hatred and discrimination. (At least six states still have laws barring atheists -- who make up between 4 and 13 percent of the U.S. population -- from holding public office.)
