In order to establish a 'church,' of like-minded individuals (which has its pros and cons), one has to codify a number of tenets. The real problem is that people have tended to imbue their doctrines with such 'numinosity' that the doctrines have become fixed dogmata that are treated like the Holy Object themselves. To then contradict or disagree with a set formula, is 'blasphemy!,' 'anathema!,' 'heresy!,' and one is then punished ('corrected'). Since I am of the belief that 'power corrupts,' and that perverse people use power in the service of sex, and sex in the service of power, all kinds of heavy sadistic practices are able to be practiced by the perverts who have gotten into the very seats of power. Witch hunts, torture, execution, burnings at the stake, persecutions in general, have always been sadistically motivated and labelled as other things by perverse churchmen.
Frankly, the only time I ever raised a fist and my voice in protest, was when Coca-Cola changed THEIR formula. Now THAT was a terrible violation, but fortunately, they recanted and changed back to the original. All was well and forgiven .
Lots of people don't know how doctrines changed over time. Most Shroomerites aren't historians, and neither am I, but even the doctrine against abortion was a complicated thing originally. It was permissable 40 days after conception for girls and 30 days after conception for boys (more of a chance to abort girls because the 'soul' was believed to enter the female body at a later date). Eventually, the doctrine changed to say that the soul entered the 'child' at the time of conception (which was believed to be at the moment of male climax, even though it takes 3 days for sperm to swim to the egg). No margin for abortion. These metaphysical doctrines were shaped by political forces more than moral or metaphysical ones, and became dogma. Violation reulted in punishment of death.
Adherence to literal, fundamental scriptural wording is the correlated problem. Saint Paul said it was a shame for a man to wear his hair long, but that it was a glory for the woman. Now, everything that Paul wrote, firstly, wasn't from Paul, but besides that, he was writng letters of encouragement to struggling churches. He was not intending to write Holy Scripture. He used the Old Testament. He also said that he was writing "by permission, not commandment" which essentially meant 'IMHO.' For hundreds of years, people have read these letters as if everything said was from God Himself. This was never the intention of the writers, it became the interpretation of 'followers.'
I cannot find an established church that I would be comfortable in. The ancient Gnostics were accused of being a hidden 5th column, that seemed to be Christians, but held heretical beliefs in their hearts. I identify with them primarily because like many Shroomerites from Fundamentalist Christian to Muslim - psychedelics have become a great Mystery in the midst of one's faith. If I were an extravert, I might form my own church at home. NOT, BTW, for donations but for a close sense of community - the original purpose for a church. Our 'ritual' might be in the taking of a mushroom, which would make us outlaws, forced to practice in hiding like the Roman christians in the catacombs beneath Rome. A few words would be devised to go along with the eating, to establish the mind 'set' that we all recognize as an integral part of the trip. And dogma would surely follow. That is, if you came over to partake, you would have to agree to some rules, like while members are lying down on a vision-quest, Thou Shalt Not Take Off Thy Clothes and Run Around the House. If you transgressed this rule (because it made certain intellectual types uncomfortable with your visceral behaviors), you would become 'Excommunicado,' thrown out of the house/church until you could return with an apology (ask forgiveness) and be admitted. No persecution in my church/house, just exile 
Dogma is just an inevitable consequence of organization, but reorganization should occur. Revolutions should occur. As Bishiop J.S. Spong entitled his book: 'Christianity Must Change or Die.'
