I went digging for the specific dialogue. These are from the translation files so if they’re a bit disjointed, it’s because I’ve gotten the paragraphs a bit out of order/missed the player asking a leading question in the middle:
That is a bold hypothesis. And yet the Omnissiah teaches us that a dauntless mind can penetrate any Knowledge through analysis. Where the ignorant see heresy, the enlightened might see truth.
There is a threat in everything. A lasgun once exploded in its owner’s hands for the first time. A cyclonic torpedo once fell on a virtuous world for the first time. Heresy was once uttered in the sacred binharic language for the first time. No thing of great power is ever safe.
But not all that is dangerous is evil. Few will dare say it in so many words, but some of our knowledge was obtained from corrupted sources. By studying the creations of xenos, we grasped profound secrets of the universe that they had discovered and we had not. By pondering heresies, we devised technological solutions to exterminate them. We drew knowledge from a poisoned well, filtered it, and attained Comprehension.
That, too… is true. I thirst for knowledge, and the Omnissiah has rewarded me with the gift of a mission to seek it. Perhaps it makes no difference to Him whether good or ill comes of the knowledge I obtain. He merely wants me to obtain it.
From the creed, yes, but not from the Omnissiah. The ancient norms have grown obsolete. What was once armour is now a prison. Mortal hands wrote the catechisms — therefore, in the name of the Deus Mechanicus, a mortal hand may edit them.
The form of prohibitions established by unknown elders. The form of an audacious violation of those prohibitions. The form of following dogma, or of schism. The form of following the Cycle, or of discontinuing the Cycle. In a system with two courses of action, schism is inevitable. And only one of these paths will be true, as truth is discretely separate from untruth.
Amarnat did not reject any one specific prohibition but found their cumulative effect to be oppressive. The system of rigid limitations had confined seekers of knowledge to a circular track, spelling doom for the thinking mind. And that cycle of repetition had to be broken. That was why he was dubbed the Messiah of Discontinuing.
Act. Amarnat pinpointed the problem of stagnation but never mustered the courage to effect change. I will effect it.
Some of this seems to tie in interestingly to this discussion on religiosity. Specifically the bit where Pasqal admits that since “mortal hands wrote our texts, so mortal hands may edit them”, which feels to me as an acknowledgement that the methods of worshiping the Omnissiah can and perhaps should change. So perhaps he’d manage to pass the hypocrisy check.
