The article's angle is that devotion to Our Lady of Guadalupe is continuing to spread to all Catholics. The article quotes Cardinal Mahony:
"The whole world's here,' Mahony said, looking at the sea of people around him. 'We are all brothers and sisters under her.'"
The only trouble with the article is that the reporter interjects the illogical, unsupportable and in fact insane opinion of "some historians" that because Our Lady appeared to San Juan Diego Cuauhtlatoatzin (He Who Speaks Like an Eagle) on the Hill of Tepeyac, where idolatry had been paid to a "goddess" of the Aztecs, then that meant that "the Virgin of Guadalupe represents a melding of two strands of belief -- Catholic teachings about Mary and indigenous traditions about the Aztec goddess..."
At least the reporter does preface that remark with the qualifier, "Although Catholic leaders disagree [with that idea]..."
The destruction of the Aztec empire by Cortez's men and their Indian allies a decade before 1531 had shattered the beliefs of the Aztecs. Their belief-world had come to an end, they no longer offered human sacrifice to keep the sun rising, yet they were still here and the world had not ended. They were without any belief and did not know where to turn.
Obviously, Our Lady appeared on the Hill of Tepeyac to show the Aztecs that they should believe in Jesus and that She was their real Mother.
Maybe someday we can build Catholic churches where abortion mills once stood.
