church of christ theology- what about a babTIZED heretic vs. a sprinkled Xian?

If only the Immersed for the remission of sins are saved, then an arian adventist (church of god general conference) goes to heaven, but a trinitarian lutheran, methodist, or presbyterian goes to hell. And don't
say "it's up to God" that is a dodge.The teaching logically infers this.
