One favorite Jesuit saint of mine somewhat in the news these days is Peter Canisius. A prayer of his:
Let my eyes take their sleep,
but may my heart always keep watch for you.
May your right hand bless your servants who love you.
And a good reminder for the times I’m tempted to become contentious online:
(I)t is a mistaken policy to behave in a contentious fashion and to start disputes about matters of belief with argumentative people who are disposed by their very natures to wrangling. Indeed, the fact of their being so constituted is a reason the more why such people should be attracted and won to the simplicity of the faith as much by example as by argument.
