You're forgetting who bore the Christ you profess to believe in. Of course Jesus is greater because He is both man and God. We're talking about Mary, stop mixing it all up. 😆 Without her we wouldn't even have Jesus. But we're getting too far from the topic.

Mary is the one who crushes the head of the serpent. Period. 😆 Ask Jesus Himself + the Holy Spirit what He thinks of that first prophecy you mentioned and for sure you will know what's up!
