Mr. President:
If part of your objective in meeting with the pope next week is to diplomatically establish common ground in such a way that he will appreciate your immigration policy and see you as an advocate of world peace, express your appreciation of how the the Catholic Church from the very beginning has always built a wall against moral corruption and built its bridge to Almighty God. Point out how this has always proved to be the path to true peace and how you are simply applying this in a political way. Thereby you will show respect for the Church he heads while providing a little nudge for him to return to the tradition of the Faith from which he has been dissenting.
