I don’t think any authentic Christian argues about what
HOLY SPIRIT
*COULD* DO
*COULD* HAVE DONE!
We like to believe that the Holy Spirit is all-powerful and He protected Mary from sin. Mary did nothing great, all of it was from God and by God, all Mary did was say yes, everything else was from God and is for the greater glory of God.If you believe that the Holy Spirit can do this and that this has nothing to do with our salvation (which came from Christ and His sacrifice) and if this doesn't contradict scripture, then quite frankly this is not an argument but just dancing around.
To Rn and Met: Do you think it impossible for the Holy Spirit to preserve a created being like Mary from sin?
