I think he is just pointing out the obvious. You are comically avoiding being honest.
I think it matters if Christians agree. Isn't that what Jesus prayed, that they, believers in him, would all be of one accord, one mind, one teaching.?..
Either God is edible or he isn't.
Either Jesus was God or he wasn't.
either following the law leads to eternal life or it doesn't.
all christian denominations profess to have hold of the truth. This is impossible given the many contradictions between their teachings.
are you saying what the actual truth is doesn't matter?
From the moment Jesus spoke of his true presence, people disagreed and went their own way--and yet Christianity and Christ's words have persisted on to this day.
It's not so much that the truth doesn't matter, but rather the truth IS--and life and the world goes on all around it. Jesus did pray that we might all be one, and that prayer continues, as does his words to not be fooled--His teachings would cause disagreements everywhere, especially within families.
I would no more stop believing in science until everyone on earth agreed on every aspect of science, than I would stop believing in God until everyone on earth agreed on every aspect of God. Everyone is in a different place on their educational journey and on their spiritual journey. Many disagreements erupt because of that reality. Even though I already knew how to tie my shoes when my children were born, I didn't expect them to be born knowing how to tie shoes. Many things we have to learn. Like science. And, especially religion/faith.
