This is one of the reasons my church deals with heresy as it does. It considers that if there is a penalty for it, then the person who makes a heretic choice has already drawn it to himself.
There was a famous conversation between the Reformed theologian Karl Bath and cardinal von Balthasar, who were good friends. Von Balthasar reportedly said “I believe in hell, but I wouldn’t surprised to learn that hell is empty”. And Karl Barth replied : “I believe in hell, but if there is anyone in there, it is Christ Himself, who took our penalty on Himself.”He’s actually, already told us in advance what will happen in the end. When asked, Jesus , looking ahead in time till the end, said Few are saved ergo everybody else isn’t. Ergo everybody else goes to Hell. And THAT comes from the one who judges ALL
This is where my church stands on that matter.
By the way, the parable of the wheat and weeds is Christ telling us what will happen at the end of times. My tradition reads it as a sign of hope rather than of fear, because it sees in it the promise of our own “internal weeds” being destroyed, and of us being totally conformed to the Kingdom of God.
