Heinrich Bullinger
Bullinger (d. 1575) . . . defends Mary’s perpetual virginity . . . and inveighs against the false Christians who defraud her of her rightful praise: ‘In Mary everything is extraordinary and all the more glorious as it has sprung from pure faith and burning love of God.’ She is ‘the most unique and the noblest member’ of the Christian community . . .
‘The Virgin Mary . . . completely sanctified by the grace and blood of her only Son and abundantly endowed by the gift of the Holy Spirit and preferred to all . . . now lives happily with Christ in heaven and is called and remains ever-Virgin and Mother of God.’
{In Hilda Graef, Mary: A history of Doctrine and Devotion, combined ed. of vols. 1 & 2, London: Sheed & Ward, 1965, vol.2, pp.14-5}
That’s the problem they’re not educated in the doctrine. I mean if they were they’d know what their protestant reformers had to say about her. Heinrich Bullinger wrote the above on the Holy Mother. What happened one might wonder.
