An anti-Catholic brought this to my attention:
From DISCOURSE IVTHE GLORIES OF MARY,
St. Alphonsus de Liguori
Hence St. Bernard with reason says, “that for this Blessed Virgin, who was to be his Mother, God created the whole world” (“Propter hanc totus mundus factus est”—In Salve Reg. s. 3). And St. Bonaventure, that its existence depends on her will. He says, addressing her, "The world which thou with God didst form from the beginning continues to exist at thy will, O most holy Virgin" (“Dispositione tua Virgo, perseverat mundus, quem et tu cum Deo fundasti ab initio”—Psalt. B. V. ps. 118); the saint adhering in this to the words of Proverbs applied by the Church to Mary: I was with Him forming all things (“Cum eo eram cuncta componens”—Prov. viii. 30).
I usually refrain from attempting any sort of ‘debate’ on YouTube, but I could not leave this unchallenged:
… did Jesus ever say that Mary was co creator “with Him forming the world…”? No He didnt, but the RCC & popes & “doctors” and “saints” of the catholic church say she was. thats heresy & blasphemy of the highest order …
This poster responded with some silliness but also with some quotes from The Glories of Mary.
The Church has never officially taught that Mary was present at creation. So what does the quote from St. Bonaventure mean? Why did St. Alphonsus de Liguori point this out?
