Your little unattributed polemic (not surprising) does not jive with the vast writings of the Reformers. Shall I provide quotes?
In no way did the Reformers attribute to Mary the blasphemous sacrilege the RCC heaps on a simple Jewish girl who was graced by God to carry the Christ child to term. The RCC ignorantly ignores Christ's own words regarding Mary as Christ tells us believers are the equal of His mother.
As far as the quote goes, I'm happy you provided me the opportunity to repost it and correctly attribute it to the second greatest mind in history...
"Nay, rather, blessed are they that hear the word of God. We see that Christ treats almost as a matter of indifference that point on which the woman had set a high value. And undoubtedly what she supposed to be Mary's highest honor was far inferior to the other favors which she had received; for it was of vastly greater importance to be regenerated by the Spirit of God than to conceive Christ, according to the flesh, in her womb; to have Christ living spiritually within her than to suckle him with her breasts. In a word, the highest happiness and glory of the holy Virgin consisted in her being a member of his Son, so that the heavenly Father reckoned her in the number of new creatures." -- John Calvin, Commentary 32
