In practice this whole mindset sounds decidedly gnostic- more like Buddhism than Judaism, if true life is living without bodily "passions".
The Buddha compared his body to an old shambles of a house that needed to be wrecked once and for all, never to be rebuilt again, and he told his followers to meditate on their bodies as rotten, oozing masses of flesh to drive that point home. He and his later followers also viewed sexuality as completely negative, at best a condescension to living a "householder" life (the sorts of people that won't reach the higher levels of enlightenment). Because the enlightened mind in the end was complete detachment from embodied existence. The Orthodox mindset doesn't sound far from that.
I'm not saying it's wrong... it's just very different from what I'd hear in a Protestant church, and perhaps it's so severe that if this mindset were embraced by everyone, it would destroy civilization and lead to a quietistic acceptance of injustice (something Buddhism has been frequently criticized for doing).
