Not so. I know what the scriptures say about these things that your church tries to claim they are found in Scripture. Trying to say that Mary never sinned because she was supposedly prevented from doing so is assertion without a fact.
All we have from the apostles are their writings. Because of this we are limited by what we can say is true. To go beyond what the Scriptures say is to speculate and that is what the catholic church does when it says she was without.
They may not have written about these things in a systmatic theological way but we do know how to interpret their writings in context. We do in fact have a very good idea what they believed about these things.
And were not the Scrptures themselves used as the foundation to refute these heresies?
I don’t start off with the premise that i beleive many catholics do i.e. that the church cannot err in matters of faith and morals. Rather i look for the support for these doctrines in the scriptures. Do the apostles teach she never sinned? Do they teach she was immaculately concieved? If anyone would know it would be the apostles. I would suspect Luke or John who probably knew her best never mention such a thing about her. This in itself should tell you that such a belief about her was totally unknown in the
1st century. To continue to say so is to believe in speculations which have no basis in Scripture.
JA4, again, Mary chose not to sin. She never resisted God’s grace. Luke assures us that she was “full of grace”. We are all free to resist God’s grace, so grace does not absolutely prevent us from committing personal sins. But God did preserve Mary from the stain of original sin at the moment she was conceived. By the way, you do not know what Scripture has to say about Mary’s sinlessness. Apart from Sacred Tradition you cannot know much of anything contained in Scripture, but only accept the Catholic doctrines you actually prefer for personal reasons. For Christ promised to send the Holy Spirit to guide his apostles and their validly ordained successors (the Episcopacy and Magisterium) in all truth in the formulation of Church doctrine.
