Blood is not sinful - & their prayers would be nothing if they were not the Prayer of Christ. Unless they have some source of grace within themselves - but that would make their salvation by God needless: why bother to save those who need no salvation ? But to have grace from oneself, is to need no salvation - it is to be God.
I therefore think that this DNA stuff “strongly points a finger” towards the probability of Mary’s Immaculate Conception (which I have taken on Faith, decades before I heard this DNA discovery).
Union with God is founded on grace, not biology - as for the prayers of the saints, they have no source of efficacy at all except the grace of Christ. Had Mary been a prostitute, her prayers would be of no less efficacy now: because the Life of the saints, in earth & heaven, is that same Christ. But as for biology - the NT is largely a protest against the notion that biology as such has any relevance to God’s favour. ## [FONT=Arial]
While you and I on earth have long ago taken this Mary stuff “on Faith”, a miracle is simply “icing on the cake”. For “Protesters”, no miracle will do the trick.
[FONT=Georgia]If that is aimed at Protestants - maybe they not convinced by miracles as such. If so, they are quite right not to be. ##[/FONT][/FONT]
[FONT=Arial]It did not when Christ walked the earth and it will not change protesting minds in our own era. Nonetheless, I take miracles if they come my way, but do not need them to believe. I hope this helps.
If Mary was so perfect that even her DNA - assuming, what there is no reason to think, let alone believe true in the first place - was affected: this line of reasoning makes her far too perfect; it exempts her entirely from the imperfections of the world of which she was a part.
If Jesus was not spared any of the consequences of the sinfulness of the world - why should she be ? We’re not - so neither was He. We are plunged in corruption - and so, for sakes, was He. To exempt His mother from being affected by the crappiness of the world, is to say she is too perfect to be really human. Which is either to deify her, or to turn her into a sort of incarnate Platonic Form, or to say she is sub-human; none of these are Christian. The servant is not greater than his Master - & neither is His handmaiden.
IOW, it seems we have a Chalcedonian Christ, but an Apollinarian Mary. Apolllinaris was so concerned to insist on the Godhead of Christ, that he ended by sacrificing His True Humanity to it: which is what has happened to Mary here.
Besides, miracles are of no importance - not unless they have an ethical purpose. Without that, they are mere “wonders” - & those are anything but characteristic of Christianity: antiquity is stuffed with wonder-workers.
As for taking things on faith - if we could prove what we believe, by specifically scientific means, faith would be needless. More than that - it would be destroyed. But science is no more capable of proving those things which are known by only by faith than one can use a thermometer to test whether a book is worth reading - people capable of doing that, would show only that they no idea of the right use of a thermometer, or of how to criticise books.
(BTW, being a Catholic does not oblige anyone to fall for every cock-and-bull story in which the word “miracle” occurs. Miracles are nothing, even if they metaphysically miraculous - a single real virtue in a man is worth ten thousand of them.) ##
