Actually all people can be made sinless. That is what Christ’ atoning sacrifice on the Cross is about. We all can through grace, repentence and His mercy be freed from our sins. The problem is when we turn away from His will and fall into sin again. If we could not be made free from sin by His grace we would have no hope of heaven. None. Hell is our default destination.
So Christ died to take away our sins. He took away Mary’s sin ( in Catholic teaching) from the moment of her conception. He in His mercy, will I pray take away my sins as I repent.
This is circular reasoning, she is either a co-redeemer as the Catholics claim, or she is one of those redeemed.
She can’t be both, that would imply she can redeem herself.
So what is she, a co-redeemer, or one of the redeemed?
“Christ died to take away our sins. He took away Mary’s sin ( in Catholic teaching) from the moment of her conception.”
In Catholic teaching is the ONLY place Mary was made sinless from her conception. Finally it’s in the light - the RCC made it up!
People are never sinless - we are cleansed from our sin by the blood of Christ and imbued with His righteousness. It’s Christ in the Christian that is without sin. As long as a human draws breath, he will sin. As did Mary, mother of Jesus, but NOT “Mother of God”.
