A suggestion for the first memento of the Roman Canon: "Remember Lord your servant Pope Emeritus Benedict!"
Since the resignation I have been saying every Mass thus, to keep the Emeritus Pope in the heart of the prayer of the Mass daily.
Oremus pro pontifice emerito nostro Benedicto
Dominus conservet eum,
et vivificet eum,
et beatum faciat eum in terra,
et non tradat eum
in animam inimicorum eius.
et vivificet eum,
et beatum faciat eum in terra,
et non tradat eum
in animam inimicorum eius.
