What is the pedigree of these words from "Jesus" and from "Our Lady"?
The web page did not provide any of this information.
Next, why is the phrase "Rosary of the Unborn" a registered trademark? (Its US Patent and Trademark Office registration # is 78087447, filed on October 8, 2001)
The only reason I can think of is that it is associated with this product:
Next, I find it strange that most of these so-called apparitions occurred AFTER the date that the trademark was applied for.
Finally, one of the "messages" apparently came from St. Thomas Aquinas (on 10/7/2002). Now, maybe somebody more experienced than I could correct me, but I don't recall ANY approved apparitions from the saints. Our Lord, yes. The Blessed Virgin, yes. But, from St. Thomas Aquinas? I don't think so.
Bottom line is that I think that this is a scam.
Having said that, by all means pray the Rosary. Pray the Rosary for the Unborn (note that this is not the trademarked expression). In fact, EWTN has an MP3 of a Rosary for Life that you could pray.
But what this website is offering uses the Faith to market a product. I believe that this is sort-of related to the sin of Simony.
No, saints other than Our Lady have appeared in visions of seers. For example, St. Joseph appeared with the Christ Child at Fatima right before the Miracle of the Sun, and St. Gabriel Possenti appeared to St. Gemma Galgani, even before he had been canonized.
