From Pope Francis Announcement of the Jubilee:
“Jesus’ reminder urges each of us never to stop at the surface of things, especially when we have a person before us. We are called to look beyond, to focus on the heart in order to see how much generosity everyone is capable of. No one can be excluded from the mercy of God; everyone knows the way to access it and the Church is the house where everyone is welcomed and no one is rejected.”
