Both the Apostles Creed and the Nicene Creed (which is recited at every Mass)states the belief in God, and Jesus Christ, etc., I would think this covers the "born again" requirements, or have I lost it?
It is also recited in many protestant churches. I think being "born again" is great, especially if someone is sincere.
I am not sure about the "not losing your salvation once you are 'born again'." I still think you can permanently separate yourself from God through sin at any time during your life. That is why repentance and forgiveness is so important. You don't just ask for it once in your life and your done. At least I don't. I have to constantly ask for forgiveness(that is done at Mass also as well as through confession).
What are your thoughts?
