Newman on Mary

"It was not enough in accordance with that heresy to proclaim Him as having an ineffable origin before all worlds; not enough to place Him high above all creatures as the type of all the works of God’s Hands; not enough to make Him the King of all Saints, the Intercessor for man with God, the Object of worship, the Image of the Father; not enough because it was not all, and between all and anything short of all, there was an infinite interval.  The highest of creatures is levelled with the lowest in comparison of the One Creator Himself.  That is, the Nicene Council recognized the eventful principle, that, while we believe and profess any being to subsist in a created nature, such a being is really no God to us, though honoured by us with whatever high titles and with whatever homage.  Arius or Asterius did all but confess that Christ was the Almighty; they said much more than St. Bernard or St. Alphonso have since said of the Blessed Mary; yet they left him a creature and were found wanting. . . .  The votaries of Mary do not exceed the true faith, unless the blasphemers of her Son came up to it.  The Church of Rome is not idolatrous, unless Arianism is orthodoxy."
