Prayer has been an essential part of Christianity since its earliest days. Prayer is an integral element of the Christian faith and permeates all forms of Christian worship. Prayer in Christianity is the tradition of communicating with God, either in God's fullness or as one of the persons of the Trinity.

In the early Church worship was inseparable from doctrine as reflected in the statement: lex orandi, lex credendi, i.e. the law of belief is the law of prayer. The Lord's Prayer was an essential element of the meetings of early Christians, and over time a variety of Christian prayer emerged.

Christian prayers are diverse and may vary among Christian denominations. They may be public prayers (e.g. as part of liturgy) or private prayers by an individual. Prayers may be performed as petition (or intercession), thanksgiving, blessing (or benediction), praise or confession.

A broad, three stage hierarchical characterization of prayer begins with vocal prayer, then moves on to a more structured form in terms of Christian meditation, and finally reaches the multiple layers of contemplative prayer. Contemplative prayer follows Christian meditation and is the highest form of prayer which aims to achieve a close spiritual union with God. Both Eastern and Western Christian teachings have emphasized the use of meditative prayers as an element in increasing one's knowledge of Christ.

Siraj Wahhaj (born Jeffrey Kearse, March 11, 1950) is an African-American convert to Islam. He is imam of Al-Taqwa mosque in Brooklyn, New York and the leader of The Muslim Alliance in North America (MANA).

Wahhaj was born as Jeffrey Kearse and raised in Brooklyn, New York. His mother Gloria Sage was a nurse and his father a hospital dietitian. His brother is writer and editor Gregory S. Kearse of Silver Spring, Maryland. He went to church religiously and went on to become a Sunday school teacher as a teenager in a Baptist church. Wahhaj then later went on to the New York University on a partial scholarship. He also played basketball where he met a teammate who interested him in the Nation of Islam, an African-American movement.

In 1969 he ended his schooling and joined the Nation of Islam, changing his name to Jeffrey12x. During this time he was vocal in his belief that “white people are devils." He said of this, “I preached it. I taught it.” Wahhaj says of his interest in the Nation: "It wasn't the theology that attracted me to the Nation of Islam at all... It was the kind of do-for-self black pride."

Benedict XVI (Latin: Benedictus PP. XVI; Italian: Benedetto XVI; German: Benedikt XVI.; born Joseph Aloisius Ratzinger on 16 April 1927) is the 265th Pope, a position in which he serves dual roles as Sovereign of the Vatican City State and leader of the Catholic Church. As pope he is regarded as the successor of Saint Peter. Benedict XVI was elected on 19 April 2005 in a papal conclave, celebrated his Papal Inauguration Mass on 24 April 2005, and took possession of his cathedral, the Archbasilica of St. John Lateran, on 7 May 2005. A native of Bavaria, Pope Benedict XVI has both German and Vatican citizenship.

After a long career as an academic, serving as a professor of theology at various German universities—the last being the University of Regensburg—he was appointed Archbishop of Munich and Freising and cardinal by Pope Paul VI in 1977. In 1981, he settled in Rome when he became Prefect of the Congregation for the Doctrine of the Faith, one of the most important dicasteries of the Roman Curia. From 2002 until his election as Pope, he was also Dean of the College of Cardinals, and as such the primus inter pares among the cardinals. Prior to becoming Pope, he was "a major figure on the Vatican stage for a quarter of a century" as "one of the most respected, influential and controversial members of the College of Cardinals"; he had an influence "second to none when it came to setting church priorities and directions" as one of Pope John Paul II's closest confidants.

Jacqueline Marie "Jackie" Evancho ( /iːˈveɪŋkoʊ/ ee-VAYNG-koh; born April 9, 2000) is an American classical crossover singer who has gained wide recognition at an early age.

Between 2008 and 2010, Evancho entered several talent competitions; made singing appearances, mostly in Pennsylvania; issued an independent album, Prelude to a Dream; and attracted interest on YouTube. Later in 2010, at the age of 10, she gained wider popularity with her performances in the fifth season of the America's Got Talent (AGT) competition, finishing in second place. With the subsequent release of her O Holy Night EP, she became the best-selling debut artist of 2010, the youngest top-10 debut artist in U.S. history and the youngest solo artist ever to go platinum. In June 2011, her first full-length major-label album, Dream With Me, debuted at #2 on American album charts, and she became the youngest top-5 debut artist in UK history. Billboard ranked Evancho the top Classical Albums Artist for 2011.

Evancho impressed composers Tim Janis and David Foster, each of whom included her in his concerts beginning in 2009. Foster later produced Evancho's album, Dream With Me, and subsequent PBS special for the television series, Great Performances. Evancho performed in front of U.S. President Barack Obama at the 2010 National Christmas Tree lighting in Washington, D.C. She is the ambassador for "Mission: Humane", a Humane Society program which encourages children's involvement in the protection of animals. She features songs from Dream With Me in a 2011–12 concert tour with symphony orchestras. Evancho released another studio album, Heavenly Christmas, in November 2011. The same month, she became the youngest person ever to give a solo concert at Lincoln Center in New York City. A national cotillion organization listed her as one of the "ten best-mannered people of 2011".
