Our Catholic president-elect offered the country this reference at the end of his speech Monday night, with a nod to both scripture and a familiar Catholic prayer:

We faced difficult times before in our history. I know we’ll get through this one, but together. That’s how we get through it, together. So as we start the hard work to be done, may this moment give us a strength to rebuild this house of ours upon a rock that can never be washed away. As in the Prayer of St. Francis, for where there is discord, union, where there is doubt, faith where there is darkness, light. This is who we are as a nation. This is the America we love and that is the America we’re going to be. So thank you all and may God bless you. And may God protect our troops and all of those who stand watch over our democracy. Thank you.

Sharp-eyed Catholics will note that he took some liberty with the words. The traditional text: 

Lord, make me an instrument of your peace:
where there is hatred, let me sow love;
where there is injury, pardon;
where there is doubt, faith;
where there is despair, hope;
where there is darkness, light;
where there is sadness, joy.

O divine Master, grant that I may not so much seek
to be consoled as to console,
to be understood as to understand,
to be loved as to love.
For it is in giving that we receive,
it is in pardoning that we are pardoned,
and it is in dying that we are born to eternal life.
