“Catholic respect for Mary is dulia/hyperdulia, not latria - the latter of which is reserved for God alone.
Ligouri was writing at a time when Marian devotion was under attack. If you read his “Glories of Mary” thoroughly, it is abundantly clear that Mary is “only a pure creature” who “receives whatever she obtains as a pure favor from God.” Further, “Jesus... has supreme dominion over all, and also over Mary.”
Catholic dogma on Mary contains four elements: Divine Motherhood, Perpetual Virginity, Immaculate Conception and the Assumption.”
None of which is supported in the scripture. Thus the Catholic retort that they do not deify Mary is in vain. Because they deify her as something more than man, and give her all sorts of devotion and place her on the way to salvation as a mediatrix, which is really through Christ only, and then protest “But we don’t think she is GOD! Just the MOTHER OF God, all-Holy ever-virgin seat of wisdom perpetual virgin whose prayers can deliver us from DEATH.”
Either salvation is ALL of God, or it is NOT. The Romans cannot make up their mind and pretend they can have it both ways.
Really? You don't believe that the being Mary bore is Eternally God (that's what "Divine Motherhood" means, BTW)? Then you reject Christianity itself.
What isn't found in the Bible is the idea that all Christian doctrine is found in the Bible.
Either salvation is ALL of God, or it is NOT.
What also isn't found in Scripture is this kind of Ockhamite "either/or" nominalism. God involves people in his plan of salvation at every stage. He's God, he's sovereign, he makes the rules, and he gets to do that.
Again, Catholics do not “deify” Mary, which means “to worship as a god.” Veneration is not deification.
