That what isn't a problem? You need to be much more clear in your communication. I don't know if you're asking about Marianne Williamson or UberMink. There isn't really a problem if someone quotes something from a non-Christian that is truthful. It becomes a problem if they endorse everything the person says.So does that mean that it isn't a problem then?
If you're asking about Marianne Williamson and her beliefs, which is what most of the discussion has been about, then, yes, that is a big problem. That is what I have been arguing. Williamson is mingling Christian belief, or at least Christian language, with New Age beliefs and spirituality. It is a path that will lead many astray and give them a false hope in a false gospel based on a false Christ. The Bible does not look kindly on people who do that. It refers to them as false teachers.
There simply is nothing in Marianne Williamson's beliefs, as seen in statements on her own website and the one given in the OP, that she is a Christian. She says empty things that appeal to people. It is precisely the type of thing Paul is referring to in 2 Timothy:
2Ti 4:3 For the time is coming when people will not endure sound teaching, but having itching ears they will accumulate for themselves teachers to suit their own passions,
2Ti 4:4 and will turn away from listening to the truth and wander off into myths. (ESV)
