"On this third Sunday of Advent, known as the Sunday "of joy", the Word of God invites us on the one hand to joy, and on the other hand to the awareness that existence also includes moments of doubt, in which it is difficult to believe. Joy and doubt are both experiences that are part of our lives. … Advent is a time of grace. It tells us that it is not enough to believe in God: it is necessary to purify our faith every day. It is a matter of preparing ourselves to welcome not a fairy-tale character, but the God who challenges us, involves us and before whom a choice is imposed. The Child who lies in the manger has the face of our brothers and sisters most in need, of the poor who are "a privileged part of this mystery; often they are the first to recognize God’s presence in our midst"."
