Peace is a gift that comes through prayer and through small daily efforts to sow harmony in one's family, parish and community, Pope Francis said.
"At the beginning of this new year, we are all called to reignite in our hearts a spark of hope, which must be translated into concrete works of peace: You don't get along with that person? Make peace. In your home? Make peace. In the community? Make peace. At work? Make peace," he said Sunday during his midday recitation of the Angelus.
"Peace is not just an absence of war, but the general condition of the person who is in harmony with him- or herself, in harmony with nature and in harmony with others," he said during the Angelus address.
Everyone says they want peace, Pope Francis said, but they continue to make war, even on a small scale. "How many families, how many communities -- even parishes -- are at war," he said.
Describing Mary as the "queen of peace," the pope said that during her earthly life she knew difficulty, "but she never lost her peace of heart, a fruit of having abandoned herself with trust to the mercy of God. We ask Mary, our tender mother, to point the whole world to the sure path of love and peace."
Reciting the Angelus Jan. 1, he reminded people that the theme of his 2015 peace day message was "No longer slaves, but brothers and sisters."
"War makes us slaves always," he said. "We are all called to combat every form of slavery and build brotherhood. And remember, peace is possible."
Faith helps make people free, and living the tenets of faith helps make them peacemakers, he said.
"Thanks to our baptism, we were introduced into communion with God and we are no longer at the whim of evil and sin, but we receive the love, tenderness and mercy of the heavenly Father," he said.
Earlier Jan. 1, Pope Francis celebrated Mass in St. Peter's Basilica and focused his homily on Mary as both the mother of God and mother of the church.
"Jesus," he told the congregation, "cannot be understood without his mother," the one who gave him human flesh, raised him and was near him always, even as he died on the cross and rose from the dead.
"Likewise inseparable are Christ and the church," he said. And, just as Mary brought Jesus into the world more than 2,000 years ago, the church continues to bring him to the world, he said.
Pope Francis repeated what he has said in the past: "It is not possible to love Christ without the church, to listen to Christ but not the church, to belong to Christ but not the church."
The church brings Christ to people, nourishes people with the sacraments and helps them understand what it means to belong to Christ, the pope said. "Our faith is not an abstract doctrine or philosophy, but a vital and full relationship with a person: Jesus Christ, the only-begotten Son of God."
"Where can we encounter him? We encounter him in the church, in our hierarchical, holy mother church," he said. "It is the church which says today: 'Behold the Lamb of God.' It is the church which proclaims him. It is in the church that Jesus continues to accomplish his acts of grace which are the sacraments."
"Without the church," the pope said, "Jesus Christ ends up as an idea, a moral teaching, a feeling. Without the church, our relationship with Christ would be at the mercy of our imagination, our interpretations, our moods."
