What about JW’s do you consider unchristian? BTW, I’m not one of those, but had an old relative who was one.
I consider the whole thing unchristian. If you read on them and you’re a Christian, it’ll be easy to see why.
Basically, like many others, they’ve twisted scripture to their ends and added or taken away certain things to get their result.
There are a lot of things out there that appear close to the truth, but indeed aren’t. Remember the bible tells us that even Satan can appear as an angel of light.
We must always be diligent and in his word and pray for the ability to tell the good from the bad (discernment).
Don’t misunderstand me though, there are a lot of good people that are JW, Catholic, Buddhist or whatever else, but being good doesn’t save a person.
