There is something in the Pope's document that the Anti-Defamation League probably didn't notice, but should:
"Art. 2. In Masses celebrated without the people, each Catholic priest of the Latin rite, whether secular or regular, may use the Roman Missal published by Bl. Pope John XXIII in 1962, or the Roman Missal promulgated by Pope Paul VI in 1970, and may do so on any day with the exception of the Easter Triduum. " (My emphasis.)
In other words, the Triduum is not part of the general permission granted in Article 2. The prayer the Anti-Defamation League finds offensive is used only once a year, during the Triduum and hence, it falls within the restriction of Article 2. Perhaps the Pope set this restriction in part out of respect for Jewish sensibilities, though it is more likely that concern for the integrity of parish celebrations of Easter was more decisive. (It would be contrary to the spirit of the liturgy for a parish to have two Easter vigils!) At any rate, it seems worth bringing to the attention of anyone who might comment negatively on the Motu Proprio in that vein.
