So you are good with anti-Trinitarians?
Honestly, I believe God judges people according to their consciences, and their hearts. If a person is not some terrorist, satanist, nazi hatemonger, or any other of that ilk which by definition hates God and his neighbor, then yes, I do believe a person of good will has a chance at Heaven. If they are, within the scope of their belief, honoring God as they perceive Him, and are kind to those around them, and do their best not to succumb to hate, then, yes, I do believe. Blessed are the peacemakers. I could picture Gandhi in Heaven- but the last word always belongs to God... May He bless you and yours!
