Does John 3:16 Mean that No matter what your " Christian affiliation"- you will get Salvation?

That's about the size of it. But then think about what it means to believe - it's not enough to just give it a nod and then go about your evil ways. To believe means to become a follower; a disciple; and live as Jesus taught. So what did Jesus teach? Well that depends how your particular brand of Christianity interprets the rest of the biblical message. And therein lies the irony. Of course you can make your own interpretation and come to your own understanding...
