I am guessing you made that up since we know the bible meaning of the bible word, Saviour...Savious means deliverer...
And if we connect the Old Testament word Savior we get a full definition...We are delivered from something and we are delivered to something...
Saviour
ישׁע
yâsha‛
yaw-shah'
A primitive root; properly to be open, wide or free, that is, (by implication) to be safe; causatively to free or succor: - X at all, avenging, defend, deliver (-er), help, preserve, rescue, be safe, bring (having) salvation, save (-iour), get victory.
Jesus is a 'full service' Saviour...
So yes, Mary knew she needed a Saviour just like we do...Somehow, Catholics don't need a Saviour as the article clearly implies...Good luck with that...
Savior: I’m seeing among those: “to cause to be safe,” “to free or succor;” “help, preserve,” “rescue,” “defend.” That’s a lot of synonyms that don’t mean to restore. And “deliver” is only one of fourteen, and even that doesn’t mean anything like, “restore,” “repair,” etc. In absolutely none of those is there any sense of something which was lost being returned. In fact, `
Catholics, on the other hand, are baptized following the Minor Rite of Exorcism, because, unlike Mary, we are not born sinless. And the article implies nothing otherwise.
