You don’t think “words” are necessary now? Neither does the Pope. We talk too much about abortion and homo-marriage, right?
Think about it, though. Sixty years ago, both abortion and homo-marriage were universally illegal and considered immoral.
Now that both are legal, almost universally, now is the time to talk about it! It’s “necessary”, as St Francis says.
To correct you, St. Francis with his whole life.
Words are very important, but what is more important is by how we live our lives.
