The statement you just uttered is blasphemous!!! What arrogance and audacity!!! Who gave you the authority to change what God has stipulated in His word?
God said that both Jews and Gentiles are all under sin: As it is written, there is none righteous, no, not one: There is none that understand: they are all gone out of the way: they are together become unprofitable, there is none that doeth good, no, not one. Romans 3
For all have sinned and come short to the glory of God. Romans 3:23
...and so, death passed upon all men, for that all have sinned. Romans 5:12
According to the Scriptures above, by definition and without exception, including Mary as well, all are sinners. Therefore, to become saved we need a Savior and that is the picture Mary illustrated in her Magnificat. She too needed a Savior. She stands on the same ground with all children of God
When we went to grade school, did our teacher give us a French book to study English? No! Likewise, to learn the things of God, we consult the Bible as it is the ultimate sourcebook of truth. Or, not any other books, or commentaries. Don’t get me wrong. Commentaries are a “help” only if the writer is faithful to the Word. And, not because he has a doctorate signature in front of or after his name, for his best work is still tainted by sin no matter how holy the text may seem, or that, the writer has a good reputation. This is the reasons I don’t read commentaries or in man’s traditions, for fear that if I read something about the things of God, did it come from the Bible or in other sources. If it’s not in the Bible, God did not say or do it!
