Addition and multiplication are not dividing. Advanced calculus based upon such fundamentally erroneous assumptions will itself be erroneous.
Your parting wish contains a lovely sentiment, and may you too experience the peace of God in your life, but the phrasology used sounded too uncomfortably like the Muslim "peace be upon him" for my taste.
No where are we commanded to divide the Word from anything other than that which is false or of the Old Law. We have been released from the Old Law and are to live in the Spirit (Rom 7:6). The attempts to parse Scripture between what is for the Jews and what is for the Gentiles is not Scriptural.
Now something considerably less Muslim - Pax et bonum.
