If people like MSO refuse to want to evolve their knowledge and understanding of a subject with time, and just want to cling to astrological ideas of the dark ages - there is nothing we can do. Just think what would happen if all our scientists clung to past knowledge and refused to study, research, explore and progress further - we wouldn't have Pasteur's germ theory, antibiotics and modern medicine for example. The "thousands of years of inputs and observations" MSO clings to have very little relevance in our times. Who knows how correct and sincere their "obervations and inputs" were in the first place? Maybe they were influenced by the power play, dirty politics and dictatorship of the church of those times. Anyone searching for true spirituality and questioning the church's interpretion was sent to prison - and attending church has nothing to do with spirituality.
And the 9th is about philosophy (a very earth bound subject, focussed solely on a single lifetime on earth), not spirituality (which is focussed on our eternal immortal spirit which lives many lifetimes on earth and other dimensions as well). All planets have a higher (spiritual) and lower (material) quality to them - jupiter is not especially spiritual.
Why do people confuse spirituality with religion? The two have absolutely nothing in common! Spirituality means being focussed on our soul/spirit and not on the physical/material side of life. It means not identifying with this temporary human condition - our soul/spirit is eternal and has lived many lives in all sorts of different situations - rich, poor, tall, short, black, white, etc - living through all these varieties of lifetimes is supposed to give us an all-round perspective of the human condition and thus learn the meaning and importance of spiritual qualities of love and COMPASSION for ALL beings. Old or advanced souls (those who have lived hundreds of lifetimes on earth) have this innate compassion, goodness, equality, unity, brotherhood, understanding, patience, tolerance, forgiveness and acceptance.
Religions teach us hatred, intolerance, coercion, bigotry, dogma, guilt, fear and sin - what does this have to do with spirituality? Religion has been all about power and politics through the ages - thats why they scare people with the concepts of salvation-damnation ("follow our religion or you are damned forever"). Its definitely not a 12th house concern.

I too started exploring spirituality in earnest sometime after my saturn return - after 30. Till then I was focussed on following society's standards of what a "normal" life should be like - even though I always had the inner feeling that it was not for me. I guess its because real spiritual knowledge is not easily available - and as children we tend to automatically pick up our parent's and community's notions of these things. Around 25-30, I went through the sadness, frustration, depression, anxiety and sorrow ascribed to the 12th - because I was not happy with my job, career and life and yet, by society's standards I was being incredibly foolish (self undoing) to give it up. But I am now at peace. Most of the depression and loneliness is caused by my saturn opp venus.
Saturn is not "hidden" in the 12th - it is just being very patient (because the 12th is a spiritual, patient, tolerant, kindly, giving, peaceful, wise, modest, gentlemanly, well-bred, selfless house) while we are young. I think all planets in the 12th are affected by this "gentlemanly" quality of the 12th - even mars behaves himself here most of the time. A gentleman goes out of his way to be good to others - even if this means inconvenience to himself - the selfish material world unfortunately sees this as a foolish, self destructive thing. This gentleman (with high morals, principles, ethics, values) gets depressed when he sees the ill-bred, selfish, superficial, corrupt behavior of the world - and thus might want solitude and isolation, and maybe a few drinks.
