It seems to change with the season. Fish on Friday, pray to Mary, Latin to English in the liturgy, etal.
In your Genesis quote, it is better to include the whole thought. God placed "enmity" between the woman (Eve) and the serpent. Very few women like snakes!
But, the reference about her seed ONLY points to Jesus, our Savior.
...as Charles Spurgeon wrote on serpents...Let your tears fall because of sin; but, at the same time, let the eye of faith steadily behold the Son of man lifted up, as Moses lifted up the serpent in the wilderness, that those who are bitten by the old serpent may look unto Jesus and live. Our sinnership is that emptiness into which the Lord pours his mercy.
Bingo !
