Because I write according to my conscience. The adherents of the principle are supposed to enable true freedom of the original mind by teaching a higher moral authority that can elevate conscience to a higher level of goodness. The principle according to Moon teaches that the good ends justify the evil means. Divine Law according to Catholicism on the other hand teaches that the evil means do not justify the good ends. By associating and interacting with evil you manifest and embody it.
Principle contradicts itself when on the one hand the ends justify the means, but also, that we should not have any kind of give and take action with evil. To do so develops the evil mind and we center on Satan instead of God. We continue to make conditions through which we form a reciprocal base of interaction with evil.
So I express my opinion in accordance with the level of conscience that I currently have through reason and guided by a higher moral authority. It’s a process that is ongoing. Catholics may consider Jesus’ teaching, or their church, or their local priests to be a higher moral authority just like Unificationists may do the same with Moon, his words, and his teaching, or the current teaching of the people in authority in the unification movement.
The challenge is to seek out and find the higher truth (moral authority). Divine Principle is supposed to be that higher truth. It seems that the authority of the words (the truth) is being replaced by the authority of the people currently in charge of the group. People are expected to conform to Divine Law - not the other way around. Ultimately God has that higher truth that can elevate the standard of our conscience. You could equate the understanding of Divine Law with the concept of the Principle.
So if you see something wrong, or feel uneasy about something then it’s most likely God guiding you through your inherent conscience. Everyone has one. We can obey or disobey but the responsibility is still ours if we do not follow it. Established authority will always seek out dissenters and eliminate them through whatever means they can to maintain the status quo and protect the corrupt authority.
It is better to face the hard cold reality than to live in unreality. It is better in the long run to face the world and do what is right, than to live in ignorance and delusion.
So if you see corruption or ineptitude in the mother church - then just like the Catholics with their church or unificationist’s with their current incarnation of the unification movement - then we have a responsibility to point out what is wrong so that it can be examined. It’s kind of like the conscience on a different level.
