Ruka does have a point, there are a lot of quacks out there with the new age stuff, and it can get confusing to a novice. I read a lot of stuff in my college years, and sure enough, a lot of what's out there sounds good, but is really worthless, and has no practical value.
As for the 12th house, twelfthnight, it is said that it deals with the dissolution of the ego, but you have to face the ego first and know all the forms it comes in to dissolve it. Some ppl just dissolve it the easy with with drugs and alcohol and thats the problem of the 12th house.. It's the house where you go to face your inner demons, and if you're lucky, you can come face to face with God, Christ, or angels. But this is a house infamous in astrology for a variety of problems, specifically the ones I mentioned above. The 12th house rules prisons, hospitals, hospices, rehab, and all places far from society. When you think about it, Jesus circulated among the people, which is a very Aquarian thing. He would have been of no use to us in the Piscean Age if he meditated in the desert and died unknown now, would he?
12th house is a retreat from the world, and not necessarily sharing what you learn there, as you face your own karma here as well. Aquarius, right next door to Pisces makes sense to share in some of the Christ consciousness in the 12th. In fact, as Aquarius is known for being cool and detached from being too emotional, his mastery of emotions would show in his control over the jar of water he's pouring out for humanity. We're thirsty for knowledge, but too much water, and we drown.
Anyway, I'll just use myself as an example. I was born with my Sun in the 11th, and was way more sociable than I am now. My philosophy is more Buddhist now, and my work more inward, and the 12th house is all about inner work. You still have compassion for the world, or it could be the opposite fish of Pisces, and have total contempt for the world. It's this very type of confusion that keeps people in the 12th house there for a long time, and they need to be there for a while to figure it all out. My sun is progressed to the 12th, so I can tell you from experience.
Long story short, I think your view of the 12th is a bit too idealistic. This house is notorious in astrology for its confusing nature. 11th house humanitarianism, and work for social reform is more in line with Christ-consciousness, and what Christ actually did in his lifetime.
BUT, there is a loophole here, as the flip-side to the person who's miserable in the 12th house, is the compassionate worker who sacrifices his life to help that person. This is where you find your saints, martyrs, even your drug-counsellors, priests, etc, who take on people's "sins" as their own. They can be said to have a Christ-consciousness, or at the least, a deep empathy and understanding of the suffering of others, so you do have a point. But the "new age" Christ may be a bit more technologically savvy and revolutionary, and who doesnt come to bring peace, but a sword.
