Ron,I’m not a bible study expert like you(I read it everyday,but never got into the study part)I guess shouldn’t have used the word “error” I guess a better word is interpretation of the Bible,there are so many different versions out there(you got yours,I got mine), and if one would take any verse in the Bible and look at it there would be at least 4 or 5 different meanings from different Bibles.So you read and understand a verse from your bible probably different from way I read it from mine.
You asked how does one get to Heaven
It does not take an expert to get to know the Bible – just someone that wants to Know what it says, not what others say it says. I can show you that Jesus said when asked what are the works to do, He said “to believe in Him who the father sent” or something like that from John 6:28+29
so we look and see that He washed us, cleansed us, redeemed us, purchased us, and so on with His Blood ie. what He did at Calvary’s
cross. We see this in Isaiah 53:5, Romans 5:9, Ephesian 1:7, Colossians 1:14+20, 1 Peter 1:18+19: Rev.1:5 and by doing this He PURGED us of our sins. The key is found in John 3:16 For whosoever BELIEVES.
It does then give you sacraments or penances or Purgatory to remove your sins – those are “catholic” add ons that nullify Scriptures.
All that is required is for you to seek first – in His word with an open heart. Read it for yourself and get rid of the binding garbage found in the Catholic Church.
