Well, we agree! Some things you can try to prove, but ultimately the other person is either going to accept it or not. I feel the same way as you about proving that the words of the Bible were inspired by God. Likewise, He also gave teaching authority to the Catholic Church to select the inspired books of the canon and to teach Sacred Tradition. Both are equally important. You either accept it or not.
I also will say a few words here and there in these sorts of threads as a Jewish convert to the one true Faith, the Catholic Faith. People may not listen and can think I’m wrong, but I’m still going to scatter the seeds and then I’ll dust off my sandals. I certainly will not get drawn into the so-called “debates” that is more about putting the other person down.
I assume the good intentions and sincerely of the posters, perhaps wrongly at times, and that relieves me of any need to engage in personal tit-for-tat and ill feelings.
So disagreement with I say is not a cause to me for hurt feeling or taking offence.
But I do enjoy the give and take of debate in its best form. Eye gouging in the name of removing a splinter is not debate, it's just eye gouging.
Hopefully we can continue to objectively debate here. Cheers!
