Sermon in the context of "Expository preaching"

Divine Liturgy (Koine Greek: Θεία Λειτουργία, romanized: Theía Leitourgía, pronounced [ˈθi.a li.turˈʝi.a]) or Holy Liturgy is the usual name used in most Eastern Christian rites for the Eucharistic service.

The Eastern Orthodox Churches, Eastern Catholic Churches and Eastern Lutheran Churches believe the Divine Liturgy transcends both time and the world. All believers are seen as united in worship in the Kingdom of God along with the departed saints and the angels of heaven. Everything in the liturgy is seen as symbolic, but not merely so, for it makes present the unseen reality. According to Eastern tradition and belief, the liturgy's roots go back to the adaptation of Jewish liturgy by Early Christians. The first part, termed the "Liturgy of the Catechumens", includes the reading of scriptures like those in a synagogue, and in some places, also a sermon/homily. The second half, the "Liturgy of the Faithful", is based on the Last Supper and the first Eucharistic celebrations by Early Christians. Eastern Christians (and many other branches of Christianity) believe that the Eucharist is the central part of the service in which they participate, as they believe the bread and wine truly become the real Body and Blood of Christ, and that by partaking of it they jointly become the Body of Christ (that is, the Church). Each liturgy has its differences from others, but most are very similar to each other with adaptations based on tradition, purpose, culture and theology.

Religion is a range of social-cultural systems, including designated behaviors and practices, ethics, morals, beliefs, worldviews, texts, sanctified places, prophecies, or organizations, that generally relate humanity to supernatural, transcendental, and spiritual elements—although there is no scholarly consensus over what precisely constitutes a religion. It is an essentially contested concept. Different religions may or may not contain various elements ranging from the divine, sacredness, faith, and a supernatural being or beings.

The origin of religious belief is an open question, with possible explanations including awareness of individual death, a sense of community, and dreams. Religions have sacred histories, narratives, and mythologies, preserved in oral traditions, sacred texts, symbols, and holy places, that may attempt to explain the origin of life, the universe, and other phenomena. Religious practice may include rituals, sermons, commemoration or veneration (of deities or saints), sacrifices, festivals, feasts, trances, initiations, matrimonial and funerary services, meditation, prayer, music, art, dance, or public service.

Byzantine literature is the Greek literature of the Middle Ages, whether written in the Byzantine Empire or outside its borders. It was marked by a linguistic diglossy; two distinct forms of Byzantine Greek were used, a scholarly dialect based on Attic Greek, and a vernacular based on Koine Greek. Most scholars consider 'literature' to include all medieval Greek texts, but some define it with specific constraints. Byzantine literature is the successor to Ancient Greek literature and forms the basis of Modern Greek literature, although it overlaps with both periods.

The tradition saw the competing influences of Hellenism, Christianity, and earlier in the empire's history, Paganism. There was a general flourishing of gnomai, hagiography, sermons, and particularly historiography, which became less individual-focused. Poetry was often limited to musical hymnal forms, or the more niche epigram tradition, while ancient dramas and epics became obsolete. The influential romantic epic Digenes Akritas is a major exception.

William Whewell (/ˈhjuːəl/ HEW-əl; 24 May 1794 – 6 March 1866) was an English polymath. He was Master of Trinity College, Cambridge. In his time as a student there, he achieved distinction in both poetry and mathematics.

The breadth of Whewell's endeavours is his most remarkable feature. In a time of increasing specialisation, Whewell belonged in an earlier era when natural philosophers investigated widely. He published work in mechanics, physics, geology, astronomy, and economics, while also composing poetry, writing a Bridgewater Treatise, translating the works of Goethe, and writing sermons and theological tracts. In mathematics, Whewell introduced what is now called the Whewell equation, defining the shape of a curve without reference to an arbitrarily chosen coordinate system. He also organized thousands of volunteers internationally to study ocean tides, in what is now considered one of the first citizen science projects. He received the Royal Medal for this work in 1837.

A Baháʼí House of Worship, or Baháʼí temple, is a place of worship in the Baháʼí Faith. It is also referred to as Mashriqu'l-Adhkár, which in Arabic means "Dawning-place of the remembrances of God".

All Baháʼí Houses of Worship have nine sides and are surrounded by nine gardens with pathways, reflecting the number nine's symbolic significance. The interior comprises a prayer hall in which the seats face the direction of the Shrine of Baháʼu'lláh. Houses of Worship are open throughout the week to both Baháʼís and non-Baháʼís for prayer and reflection, with some having scheduled weekly devotional services. Scriptural texts from all religions may be recited inside, but sermons, ritualistic ceremonies, and readings from non-scriptural texts are not allowed. In addition, several Houses of Worship have formed choirs which sing music based on the Baháʼí writings, although musical instruments may not be played inside. At present, most Baháʼí devotional meetings occur in individuals' homes or local Baháʼí centres rather than in Houses of Worship.

A lecture (from Latin: lectura 'reading') is an oral presentation intended to present information or teach people about a particular subject, for example by a university or college teacher. Lectures are used to convey critical information, history, background, theories, and equations. A politician's speech, a minister's sermon, or even a business person's sales presentation may be similar in form to a lecture. Usually the lecturer will stand at the front of the room and recite information relevant to the lecture's content.

Though lectures are much criticised as a teaching method, universities have not yet found practical alternative teaching methods for the large majority of their courses. Critics point out that lecturing is mainly a one-way method of communication that does not involve significant audience participation but relies upon passive learning. Therefore, lecturing is often contrasted to active learning. Lectures delivered by talented speakers can be highly stimulating; at the very least, lectures have survived in academia as a quick, cheap, and efficient way of introducing large numbers of students to a particular field of study.
