Reformed theology is the highest form in history. It began not with Martin Luther but in Genesis. There is no other opposing theology I would follow.
However, I must also recognize, that the higher the knowledge, it does not mean the better the seekers of it. Since it is neutral, in the hands of the wicked, the disguise of the wicked is greater. So ultimately, one must be able to judge the motives of others, this is not something we leave to God alone - as many evildoers would love to convince others of.
