Leland from Virginia asked: "How serious of a heresy is Christian Universalism?"
Well, Leland, It's a huge problem. I’ll begin by stating that it's an oxymoron to put the terms “Christian” and “Universalism” together. One is heresy and one is the truth.
Here are some references to consider:
“And there is salvation in no one else, for there is no other name under heaven given among men by which we must be saved.” (Acts 4:12: ESV)
That's the gospel. That's the message that we share with our friends, neighbors, and world.
Therefore, since we have been justified by faith, we have peace with God through our Lord Jesus Christ. (Romans 5:1 ESV)
How can I know that I’m not condemned today? Is it because I'm a good person? Or because I'm sincere in what I believe? Will God give me credit for following a false god, because at least I'm trying?
No. Romans 8:1 says:
There is therefore now no condemnation for those who are in Christ Jesus. (Romans 8:1 ESV)
Universalism is a heresy that's been around for centuries and will continue to spread. Why? Because the message of Universalism is that everybody makes it to heaven. The problem is that God’s Word, while teaching that heaven is real, also teaches that hell is real. Both are realities. Universalism is a dangerous heresy because it leads millions to hell while giving them the false hope of heaven.
Salvation is something we need to be precise about, and follow God’s Word exactly. If you get it wrong, you go to hell. If you get it right, you go to heaven.
Thanks for your question, Leland,
