That is one of the most profoundly false things I have seen on this thread. Scripture is easy to quote which refutes it. We have an "imputed" righteousness through faith in Christ (Rom 3:23-24-... for all have sinned and fall short of the glory of God, 24 and all are justified freely by his grace through the redemption that came by Christ Jesus.), but we are sinners for life. We are at war with our own nature. If we could overcome sin, Christ died for naught!
Paul in his writing to that proud bunch at Rome, said in Romans 7: 13 ... Did that which is good, then, become death to me? By no means! Nevertheless, in order that sin might be recognized as sin, it used what is good to bring about my death, so that through the commandment sin might become utterly sinful.
14 We know that the law is spiritual; but I am unspiritual, sold as a slave to sin. 15 I do not understand what I do. For what I want to do I do not do, but what I hate I do. 16 And if I do what I do not want to do, I agree that the law is good. 17 As it is, it is no longer I myself who do it, but it is sin living in me. 18 For I know that good itself does not dwell in me, that is, in my sinful nature.[c] For I have the desire to do what is good, but I cannot carry it out. 19 For I do not do the good I want to do, but the evil I do not want to do—this I keep on doing. 20 Now if I do what I do not want to do, it is no longer I who do it, but it is sin living in me that does it.
21 So I find this law at work: Although I want to do good, evil is right there with me. 22 For in my inner being I delight in God’s law; 23 but I see another law at work in me, waging war against the law of my mind and making me a prisoner of the law of sin at work within me. 24 What a wretched man I am! Who will rescue me from this body that is subject to death? 25 Thanks be to God, who delivers me through Jesus Christ our Lord!
So then, I myself in my mind am a slave to God’s law, but in my sinful nature[d] a slave to the law of sin.
The Greek word for flesh (sarx) refers to the sinful state of human beings, often presented as a power in opposition to the Spirit. We are sinners, FRiend, covered by the Blood. Grace is an imputed state of righteousness, not a lifestyle...
But it HAS to be said; or else the 'sinless' claim for Mary holds no water.
Thank you.
