On the contrary, I find Ms. Bonds conclusion exactly the opposite of what I found. St Patrick is an example of a person who fought against the Pelagius error, one that the Church has long since embraced even though they don't wish to admit it. Futhermore, you'll find in "the beautiful prayer of St. Patrick, "St. Patrick's Breast-Plate", no reference to the Virgin Mary. This, "Hail Mary full of grace" stuff, came long after he left the scene. Instead he states (in part):
I bind to myself today
The virtue of the love of seraphim,
In the obedience of angels,
In the hope of resurrection unto reward,
In prayers of Patriarchs,
In predictions of Prophets,
In preaching of Apostles,
In faith of Confessors,
In purity of holy Virgins,
In deeds of righteous men.
...
Christ, protect me today
Against every poison, against burning,
Against drowning, against death-wound,
That I may receive abundant reward.
Christ with me, Christ before me,
Christ behind me, Christ within me,
Christ beneath me, Christ above me,
Christ at my right, Christ at my left,
Christ in the fort,
Christ in the chariot seat,
Christ in the poop [deck],
Christ in the heart of everyone who thinks of me,
Christ in the mouth of everyone who speaks to me,
Christ in every eye that sees me,
Christ in every ear that hears me.
