The archangel Gabriel already told her that God would be the Father of her Son and that the child would be called the Son of God. Mary and Abraham are different because she was born without the stain of original sin and thus could be much more open to God than Abraham ever could. The song in question is Protestant in nature and has no business being in any kind of Catholic liturgical service because it is not compatible with the Church’s teachings on Mary.
I do not want to derail this thread. The only reason why I mentioned this song was that I believed it was highly inappropriate to have used this song for Good Friday, after the Passion but prior to the homily, as a meditation piece. It did not make for good liturgy, and made a bad experience only worse.
I’m sorry the song didn’t work for you; I’ve never heard it in a liturgical setting, so maybe I would find it equally inapt. And I’ll limit myself to this one response, since even though the thread’s pretty much petered out I don’t want to really derail it either. (BTW, I assume we’re talking about the same song, with lyrics about like
these.)
Anyway, Luke tells us that Mary “was greatly troubled” at the Gabriel’s greeting, and that Gabriel then explained to her that her son “will be great and will be called Son of the Most High, and the Lord God will give him the throne of David his father, and he will rule over the house of Jacob forever, and of his kingdom there will be no end.” That’s all well and good, but it doesn’t explain why Mary should have known that her “baby boy will save our sons and daughters, . . . will one day walk on water, . . . give sight to a blind man, . . . calm a storm with his hand,” or even “one day rule the nations” as opposed to ruling just the house of Jacob. You can argue that she would have intuited these things, or that they were revealed to her in a way not discussed in Scripture, but that’s a matter of sufficiently deep interpretation that I don’t think the song can be said to be obviously “anti-Catholic.”
I’m not aware of any authoritative Catholic teaching that holds that Mary
knew all these things at the moment she gave her assent. Personally, I find it telling that Mary replied, “Behold, I am the handmaid of the Lord. May it be done to me according to your word,” and not, “Ah, I see your point – yes, this all sounds like a good idea.”
In the end, of course, although I think you’ve overstated the case, I fully agree with you that the song is a highly bizarre choice for Good Friday as opposed to, say, Christmas or the Annunciation, and I also agree that there are much better songs, on a variety of levels, that could be chosen on any of those occasions.
