On another thread DHK said the following: Let us take his advice and consult a dictionary. The word "moral" is defined as "of or relating to principles of right and wrong in behavior" (Merriam-Webster.com). The word pure as it relates to morals is defined as "free from moral fault or guilt" (Ibid.). So when we put the two words together we can see that morally pure refers to being free from moral fault or guilt in our behavior. So in order to be morally pure a person must not sin or he will not be free from moral fault or guilt. in other words, a morally pure state is one where there is no sin.
