Vatican City • Under the dome of St. Peter’s Basilica, Pope Francis celebrated the Christmas vigil Mass on Tuesday by reminding faithful of the redeeming power of grace and admonishing them to “take courage,” because “God loves you.”

“Do not lose confidence, do not lose hope, do not think that to love is a waste of time,” the pope said in his homily. “Tonight, love has conquered fear, new hope has arrived, God’s kindly light has overcome the darkness of human arrogance.

“Mankind, God loves you; for your sake, he became man. You are no longer alone!”

Francis said that like the shepherds who ran to the manger to see Christ, the faithful today have many failures and are “not saints.” At Christmas, he added, they are all invited and called to God, in whose presence they need not be afraid. This lesson remains true today, Francis said, as the scandals in the Catholic Church and people's personal doubts impede them from going to Christ.

“Whatever goes wrong in our lives, whatever doesn’t work in the church, whatever problems there are in the world, will no longer serve as an excuse,” he said. “At Christmas, the question is this: ‘Do I allow myself to be loved by God? Do I abandon myself to his love that comes to save me?’”

The Mass was celebrated with the typical liturgical colors of white and gold, before a large crowd of Vatican representatives and faithful from Rome and all over the world. Children from Japan, Venezuela, Kenya, Uganda, the Philippines and Iraq carried the statue of Jesus from under the altar to the creche at St. Peter’s Square at the end of the celebration.

Grace was at the center of Francis’ homily, which he described as “divine love, the love that changes lives, renews history, liberates from evil, fills hearts with peace and joy.” At Christmas, he said, grace is incarnated in the person of Jesus, “who made himself tiny, so that we might love him.”

“Tonight we realize that, when we failed to measure up, God became small for our sake; while we were going about our own business, he came into our midst,” he said. “Christmas reminds us that God continues to love us all, even the worst of us.”

The pope went on to explain that God’s love is not won by behaving in a certain way. “He loves you, plain and simple,” independently of whether one has “mistaken ideas” or “made a complete mess of things.”

“How often do we think that God is good if we are good and punishes us if we are bad. Yet that is not how he is,” Francis said. “For all our sins, he continues to love us. His love does not change. It is not fickle; it is faithful. It is patient. This is the gift we find at Christmas.”

Amid the beautiful art of St. Peter’s Basilica, Francis said that in God’s love, “we also discover our own beauty.” At Christmas, the faithful are reminded that in the eyes of God “we are beautiful, not for what we do but for who we are.”

A final lesson to be learned from this important day for Christians, the pope said, is that change can be fueled by gifting oneself to others, instead of trying to change others.

“May we not wait for our neighbors to be good before we do good to them, for the church to be perfect before we love her, for others to respect us before we serve them. Let us begin with ourselves,” Francis said. “This is what it means freely to accept the gift of grace. And holiness is nothing other than preserving this freedom.”
