"The only thing we really have to work at in this life is how to manifest love".Can't you hear the voice of Francis of Assisi? Or Julian of Norwich? Perhaps Dorothy Day? It's not about doctrine, not primarily. It's not about clobbering anyone about the ears or going on a power trip. Manifesting the love God implanted in the human soul -- sharing the love we've been given, allowing others to bring their inherent human dignity and love to the task at hand, reflecting God's compassion and mercy whenever and however we can find the strength to do so. None of us live up to that all the time. I sure don't. But the core calling is indeed to "manifest love."
