Military development. Academics. Athletics. Three pillars of Army values that cadets at America's most prestigious military academy live by.

But West Point cadet Blake Page says there is one other unspoken pillar at the United States Military Academy: religion.

That's why, with just five months left before graduation, Page quit.

And he did it in a most public fashion -- in a fiery blog post.

"The tipping point of my decision to resign was the realization that countless officers here and throughout the military are guilty of blatantly violating the oaths they swore to defend the Constitution," wrote Page, 24, in The Huffington Post.

"These men and women are criminals, complicit in light of day defiance of the Uniform Code of Military Justice through unconstitutional proselytism, discrimination against the non-religious and establishing formal policies to reward, encourage and even at times require sectarian religious participation. These transgressions are nearly always committed in the name of fundamentalist evangelical Christianity."

Page said he felt discriminated against for being nonreligious. And that discrimination, he alleged, was systematic.

In his letter of resignation, he said: "I do not wish to be in any way associated with an institution which willfully disregards the Constitution of the United States of America by enforcing policies which run counter to the same."

He said West Point made prayers mandatory and students who took part in religious retreats and chapel choirs were given extra passes. He said officers incentivized religious activities and there was generally open disrespect for nonreligious cadets.

"The problem is a lot of people don't report it," Page said.

The U.S. Military Academy confirmed that Page's resignation had been accepted and that he was being honorably discharged.

However, spokesman Francis DeMaro Jr. said Page's claim that prayer was mandatory was not true.

"The academy holds both official and public ceremonies where an invocation and benediction may be conducted, but prayer is voluntary," he said.

"As officers, cadets will be responsible for soldiers who represent America's great diversity in faith and ethnic background," he said. "The academy provides cadets the opportunity to foster an understanding regarding the fundamental dignity and worth of all."

DeMaro said West Point has a Secular Student Alliance club to meet the needs of nonreligious students.

Page went to West Point because, he said, he'd always wanted to become an officer in the U.S. Army.

After high school in Stockbridge, Ga., he enlisted and spent three years in an air defense unit. While there, his commanders encouraged him to enroll at West Point.

Page knew how prestigious an institution it was. It would be an awesome career move, he thought.

He began at West Point, Page said, as a high performer. He was encouraged to seek out challenging positions. He said his tactical officer and mentor even tried to promote him to squad leader prematurely in his sophomore year.

But later, he struggled after his father committed suicide. He was diagnosed with clinical depression and anxiety and disqualified from being commissioned as a second lieutenant, the usual next step for West Point graduates.
