ROB,
How can you say that “many people testified that he had not left his gentile ways” when not a single reliable, or even remotely believable, witness has been identified. (An army buddy of the Langer boy who married a non Jew and was totally irreligious has no neemanus in such a case. It was not even remotely meisiach lfi tumoi). In fact that statement had been conclusively disproven. (Joseph never called Borokowski a “Tzaddik Gomur” he said a share torah. Big difference).
And it is “your belief” that there was nothing unusual with Goren’s hetter, is soundly contradicted by every major Posek of the time.
So much so that if this were in time of Sanhedrin, he would likely be considered a ??? ????.
There have been disagreements over psokim in the past, but I hhave not heard the proclamations by all those same poskim say as a blanket statement that no psak of ( in this case Goren) can be relied upon. That is unusual. Go look at who made those proclamations.
It seems you accept the word of Moshe Dayan over R Shach, R Moshe, R Elyashiv, and R Shlomo Zalman, tthe Steipler, to name just a few in regards to this serious Halachic matter.
Ok. As long as it is clear.
