<forget the word trinity>

easily done.

<"do you believe the doctrine of "three persons in the one divine essence?" YES OR NO!>

a. You didn't quote Chapter nor Verse where "three persons in the one divine essence" appears in "THE WORD OF GOD". Why?

b. If that quote is man made, then it is NOT "profitable for DOCTRINE" according to "THE WORD OF GOD".

c. Does I John 5 sufficiently answer what you demand to be a "YES OR NO" answer, or NOT????? I BELIEVE everything in I John 5 which "IS PROFITABLE FOR DOCTRINE", as well as the rest of "THE WORD OF GOD" regarding WHO GOD IS.
Do you understand if it's NOT "WRITTEN" in "THE WORD OF GOD" that it neither qualifies as "DOCTRINE" nor is it worthy of a "yes or no" answer which cults like the rcc normally demand regarding their man made words which are twistable.
