"Our Mother Mary is full of beauty because [s]he is full of grace."
- Francis of Rome via Twitter about a year ago.
The typo (corrected with bracketed insertion) was amusing, but there's a bigger problem. Who is more full of grace - Mary or Jesus? Yet of Jesus it is said "he hath no form nor comeliness; and when we shall see him, there is no beauty that we should desire him" (Isaiah 53:2). Was Mary physically beautiful? No one knows, for there is no authentic tradition about her appearance. All the idols of her are lies, the mere figments of the imaginations of their creators. Little children, keep yourselves from idols.
And as well, in Scripture our mother is the heavenly Jerusalem, not Mary. (Galatians 4:26)
