Who says that all who do not follow Scripture to the very letter shall be damned ? There are many do s and dont s in our Holy Bible, but there is only one constant : God is Love. He created all His creatures out of Love. If you follow every precept in the Book, and yet have no love, as St. Paul says : " it profits me nothing." ( 1 Corinthians, vs. 3 [ read the whole of 13, gosh-darn-it, for in it is the whole of the true preaching ]) And what does Our Good Master, Our Shepherd, say about the final judgement ? There is only one allusion : Matthew 25, vs. 31- 47. Read it and imbibe it. Quote : " I was hungry and you gave me to eat ; I was thirsty and you gave me to drink...' Come, blessed of my Father, take possession of the Kingdom prepared for you from the foundation of the world..." And it is based solely on Mercy, like in the parable of the Good Samaritan. Just mercy and love for one another. Not : " you did not genuflect correctly, or ' you were late for Services,' or any other such ritualistic nonsense. God has no equal. He towers above the heavens ; the universe is but a footstool to Him. Just as a mighty earthly father delights in his first-borns first steps and rejoices, he rejoices even more when his baby stumbles and falls.
John ends his Gospel by saying : " There are, however, many other things that Jesus did ; but if everyone of these should be written, not even the world itself, I think, could hold the books that would have to be written. Amen." ( John 21, vs.25 ) And where would we store the books that could be written - if ever they could - about everything the Father did, before and in Jesus, and that the Spirit does, and continually keeps on doing ? So there is only one key : not cultual adherence, no matter which, but to " love mercy and truth, and walk humbly with your Lord."
