Archbishop Carlo Maria Viganò’s letter accusing Pope Francis of aiding the cover-up of ex-Cardinal Theodore McCarrick’s sexual abuse of minors and seminarians has put certain Vatican officials on the defensive, and is sparking some revealing reactions. Earlier this week, Cardinal Blase Cupich, the archbishop of Chicago, dismissed calls to investigate Viganò’s claims in an interview on Chicago’s NBC 5, saying “the pope has a bigger agenda, he’s got to get on with other things, of talking about the environment, and protecting migrants, and carrying on the work of the church. We’re not going to go down a rabbit hole on this.”

To paraphrase the pope’s own response to Viganò, “make your own judgment” on Cupich. Maybe the cardinal, who Viganò names in his letter as one of McCarrick’s favorites, is trying to cover his own rear; maybe he genuinely believes that recycling and border bridges are higher priorities than delivering justice for abuse victims and that “carrying on the work of the church” doesn’t include rooting out sin. Maybe some of both. But what stood out weren’t his political preferences or ideas about the church’s duties. It’s that “rabbit hole” remark.
