I was reading today about a new college president who grew up Catholic but is married to an Evangelical. In the course of trying to describe his religion he said,
I would comfortably describe myself as a born-again Christian, but I don’t feel it is necessary to renounce anything.
I found the statement very telling of our times. Understanding context, he is saying I can be a Christian but do not have to renounce Catholicism. Is he not saying, I can be a Christian, but don’t have to renounce my sin, my past, my theological errors, the sins of my works? I can be a Christian, but do not have to die to myself, my past, my former way of life? I can be a Christian, but am not truly born again, changed from death to life, but have simply evolve and progress in my religion?
According to Scripture this is an idea entirely opposed to being born again. Paul certainly did not have this view about his former religion of Judaism. Galatians 2
15 We ourselves are Jews by birth and not Gentile sinners; 16 yet we know that a person is not justified  by works of the law but through faith in Jesus Christ, so we also have believed in Christ Jesus, in order to be justified by faith in Christ and not by works of the law, because by works of the law no one will be justified.
17 But if, in our endeavor to be justified in Christ, we too were found to be sinners, is Christ then a servant of sin? Certainly not! 18 For if I rebuild what I tore down, I prove myself to be a transgressor. 19 For through the law I died to the law, so that I might live to God. 20 I have been crucified with Christ. It is no longer I who live, but Christ who lives in me. And the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me. 21 I do not nullify the grace of God, for if righteousness  were through the law, then Christ died for no purpose.
