Even if you insist on rejecting out of hand all evidence but your version of the bible because of your belief in “sola scripture”, the least you could do is appreciate that not everyone adheres to that doctrine.
Besides, the purpose of this article isn’t to prove that Mary did not sin, but merely to refute arguments that she did.
Case in point.
If the bible doesn't specifically say that a person other than Jesus sinned and/or is a sinner, then is there a biblical argument that that person is without sin? If so then there is no point to this discussion because there is no real interest in the bible here.
Besides, the purpose of this article isn’t to prove that Mary did not sin, but merely to refute arguments that she did.
The Catholic church claims it wrote the Bible. then it's not unreasonable to expect there to be Scriptural support for the belief that Mary was sinless and always virgin.
Where is it?
Is there something about *all have sinned* that is too hard for Catholics to understand?
Romans 3:21-31 21But now the righteousness of God has been manifested apart from the law, although the Law and the Prophets bear witness to it— 22the righteousness of God through faith in Jesus Christ for all who believe. For there is no distinction: 23for all have sinned and fall short of the glory of God, 24 and are justified by his grace as a gift, through the redemption that is in Christ Jesus, 25whom God put forward as a propitiation by his blood, to be received by faith. This was to show God’s righteousness, because in his divine forbearance he had passed over former sins. 26It was to show his righteousness at the present time, so that he might be just and the justifier of the one who has faith in Jesus.
27 Then what becomes of our boasting? It is excluded. By what kind of law? By a law of works? No, but by the law of faith. 28For we hold that one is justified by faith apart from works of the law. 29Or is God the God of Jews only? Is he not the God of Gentiles also? Yes, of Gentiles also, 30since God is one—who will justify the circumcised by faith and the uncircumcised through faith. 31Do we then overthrow the law by this faith? By no means! On the contrary, we uphold the law.
