Just Another Powerful Quote from Ratzinger...
Christianity is not a body of beliefs, but a way of life that contains within it a body of beliefs and those beliefs can only be known through the lived experience of the communion of saints. This is why orthodoxy and orthopraxy are always united.
“A new commandment I give to you, that you love one another; even as I have loved you, that you also love one another. By this all men will know that you are my disciples, if you have love for one another” (John 13:35-36).
