NEWMAN: UNIQUE ARGUMENT FOR IMMACULATE CONCEPTION: "The holy Daniel, when St. Gabriel appeared to him, "fainted away, and lay in a consternation, with his face close to the ground." When this great archangel came to Zacharias, the father of St. John the Baptist, he too was troubled, and fear fell upon him." But it was otherwise with Mary when the same St. Gabriel came to her. . . . she was able to bear the sight of him."
Interesting quote.
