What I find interesting about this invitation is not so much the making room for everything that the Faith itself allows as where the room is to be made: in our hearts.
You don't tolerate what's in your heart, you don't put up with it, you don't grant in principle the right for it to be. You love it.
I doubt there are many people who truly love everything that the Faith itself allows. I wouldn't say I do. I try to make room in my head for it all, but there are any number of things the Faith allows that I at best don't wish bad things upon.
Just imagine a heart big enough to love it all, a heart that actively seeks the good of the whole Faith. Nothing smaller can properly be called a Catholic heart.
Do you have it in you? Do you have it in you to have it in you?
