A typical traditional Catholic salutation/aspiration, e.g. to close a letter, which I often use is OMNES CUM PETRO AD IESUM PER MARIAM.
Now, with the direction of the present Magisterium of Pope Francis (cf.
Evangelii Gaudium) I should like to add a name..Paulus!
A Roman inspiration! Saint Peter and Saint Paul most often appear depicted together here! Even notice in the 1962 ritual that when there is a Feast for one of them there are the additional orations for the other. Their memory always goes together! So...
OMNES CUM PETRO
ET PAULO AD IESUM PER MARIAM!
A Church always ad gentes!
N.B. More on the Apostolic Exhortation to come.
