The Order of Saint Luke (OSL) is an religious order in The United Methodist Church, dedicated to sacramental and liturgical scholarship, education, and practice.
As a Christian religious order, it is a dispersed community of women and men, lay and clergy, from many different denominations, seeking to live the sacramental life. "Membership in The Order is open to persons of all Christian denominations who seek to live the sacramental life in accordance with our Rule of Life and Service, in community with and acceptance of their brothers and sisters in the Order."
The Order gathers annually in mid-October for several days of worship, fellowship, and administration.
The Order proclaims itself as Wesleyan and Lukan in its spirituality, Methodist in its origins, sacramental in its practice, and ecumenical in its outlook.
The Order of St Luke was founded in 1946 in the former Methodist Church and holds the status of Affiliate Organization with the Section on Worship of the General Board of Discipleship of the United Methodist Church. The Order was formed under the leadership of the Rev. R. P. Marshall, a former editor of the Christian Advocate. It was dedicated to the cause of liturgical renewal, and led the way in a serious liturgical awakening across the Methodist Church and much of post-war Protestantism. It was inspired partly by the existence of the Methodist Sacramental Fellowship, which serves a similar purpose in relation to the Methodist Church of Great Britain.
In mathematics, big O notation describes the limiting behavior of a function when the argument tends towards a particular value or infinity, usually in terms of simpler functions. It is a member of a larger family of notations that is called Landau notation, Bachmann–Landau notation (after Edmund Landau and Paul Bachmann), or asymptotic notation. In computer science, big O notation is used to classify algorithms by how they respond (e.g., in their processing time or working space requirements) to changes in input size. In analytic number theory, it is used to estimate the "error committed" while replacing the asymptotic size, or asymptotic mean size, of an arithmetical function, by the value, or mean value, it takes at a large finite argument. A famous example is the problem of estimating the remainder term in the prime number theorem.
Big O notation characterizes functions according to their growth rates: different functions with the same growth rate may be represented using the same O notation.
Luke the Evangelist (Ancient Greek: Λουκᾶς, Loukãs) is one of the Four Evangelists—the four authors of canonical Gospels of Jesus Christ. Luke was a native of the Hellenistic city of Antioch in Syria. The early church fathers ascribed to him authorship of both the Gospel according to Luke and the book of Acts of the Apostles, which originally formed a single literary work, referred to as Luke–Acts. Prominent figures in early Christianity such as Jerome and Eusebius later reaffirmed his authorship, although the fragile evidence of the identity of the author of the works has led to discussion in scholarly circles, both secular and religious.
The New Testament mentions Luke briefly a few times, and the Pauline epistle to the Colossians refers to him as a doctor; thus he is thought to have been both a physician and a disciple of Paul. Christians since the faith's early years have regarded him as a saint. He is believed to have died a martyr, although accounts of the events do vary.
Saint Luke (also Saint Luc, Sint Lukas, San Luca, San Lucas, ...) is Luke the Evangelist, patron saints of physicians and surgeons, and of artists. Saint Luke and its variants may also refer to:
