127.&#160; said:&#160; "But even if, as you yourselves suppose, you are following the law of the Lord in purity, let us nevertheless consider the question of the most holy law itself in a legal form.&#160; The Apostle Paul says, &#8216;The law is good, if a man use it lawfully.&#8217; &#160; What then does the law say?&#160; &#8216;Thou shalt not kill.&#8217;&#160; What Cain the murderer did once, you have often done in slaying your brethren."

&#160;128.&#160; answered:&#160; We do not wish to be like you:&#160; for there are not wanting words which might be uttered, as you too utter these; and known also, for you do not know these; and set forth in the conduct of a life, as these are not set forth by you.
