Our Blessed Mother is the intercessor par excellence. Under her title Our Lady of Fatima she has continuously urged that we offer prayer - most notably the Rosary - for peace and conversion. If you have not heard of Our Lady of America, please take note of her and her insistence upon purity and chastity as necessary conditions for restoration - both personal and societal. I link now to the site of those championing this devotion and to a letter (as it appears on the EWTN site) by then-Archbishop Burke that detailed his review and favorable opinion of this devotion.
Ora et labora.
