You could say...
"Yes it is true, that like Job, I am determined not to let any man or any organization pretending to speak for Jehovah take away my integrity.
Yes, it is also true that like Abraham, who James referred to in his letter as "God's friend" I am concerned that "The Judge of all the earth" ought not allow himself to be besmirched by his own conduct appearing to be less than moral, nor allow any man or any organization pretending to act on his instruction to represent him in a less than spotless manner remain uncontested.
It is for both of these reasons that I must take pains to point out how the WTBS has not only misrepresented the scriptures, but also the moral force of love as represented by the person of Jehovah himself.
These men have changed his word, violated the very spirit of his word, and appropriated for themselves the prerogatives of judging which he has given to his son. In this they are anti-Christ. They are certainly not the only religious group who have acted in this manner, but they are the ones whose pernicious ways have had the greatest impact upon me and those whom I loved and strill love.
You, sir, have your own garden to attend to. I suggest that you attend to it. As for me, I cannot stop speaking about the things I have seen and heard. I would be false to myself , my maker and my savior were I to remain silent in this matter."
... or something else, maybe...
