This is such a dangerous thought that is being spread through out the world. Oprah is a big supporter of this view and how many people follow what she does?
Jesus says He is the only way to the Father. No other method can be available if we believe Jesus to be true. Judaism is the foundation of Christianity. Christianity should just be Judaism with a new covenant. This new covenant is the key to salvation. Almost every religion pushes a humanistic approach to life where we should all be nice and good to people and do no harm. That is great and what God has said we are supposed to do, but when we focus on that aspect and lose the salvation offered through Jesus, then we are just a bunch of good people who are not saved.
We need to draw a line and say I will love my neighbor because that is what God commands, but our salvation is not based on that.
