Biblical SabbathThe Sabbath is a weekly day of rest or time of worship given in the Bible as the seventh day. It is observed differently in Judaism and Christianity and informs a similar occasion in several other faiths. Observation and remembrance of Sabbath is one of the Ten Commandments ("Remember the sabbath day, to keep it holy") considered to be the fourth in Judaism, Eastern Orthodoxy, and most Protestant traditions, and the third in Roman Catholic and Lutheran traditions.
Lord's PrayerThe Lord's Prayer, often known by its incipit Our Father (Pater Noster), is a central Christian prayer which Jesus taught as the way to pray. Two versions of this prayer are recorded in the gospels: a longer form within the Sermon on the Mount in the Gospel of Matthew, and a shorter form in the Gospel of Luke when "one of his disciples said to him, 'Lord, teach us to pray, as John taught his disciples.
Canon lawCanon law (from κανών, kanon, a 'straight measuring rod, ruler') is a set of ordinances and regulations made by ecclesiastical authority (church leadership) for the government of a Christian organization or church and its members. It is the internal ecclesiastical law, or operational policy, governing the Catholic Church (both the Latin Church and the Eastern Catholic Churches), the Eastern Orthodox and Oriental Orthodox churches, and the individual national churches within the Anglican Communion.
Book of RevelationThe Book of Revelation, also erroneously called the Book of Revelations, is the final book of the New Testament (and therefore the final book of the Christian Bible). Written in Koine Greek, its title is derived from the first word of the text: apokalypsis, meaning 'unveiling' or 'revelation'. The Book of Revelation is the only apocalyptic book in the New Testament canon. It occupies a central place in Christian eschatology. The author names himself as simply "John" in the text, but his precise identity remains a point of academic debate.
New TestamentThe New Testament (NT) is the second division of the Christian biblical canon. It discusses the teachings and person of Jesus, as well as events in first-century Christianity. The New Testament's background, the first division of the Christian Bible, is called the Old Testament, which is based primarily upon the Hebrew Bible; together they are regarded as sacred scripture by Christians. The New Testament is a collection of Christian texts originally written in the Koine Greek language, at different times by various authors.
Divine LiturgyDivine Liturgy (Theia Leitourgia) or Holy Liturgy is the Eucharistic service of the Byzantine Rite, a liturgical rite developed from the Antiochene Rite of Christian liturgy which is that of the Ecumenical Patriarchate of Constantinople. As such, it is used in the Eastern Orthodox, the Greek Catholic Churches, and the Ukrainian Lutheran Church. Although the same term is sometimes applied in English to the Eucharistic service of Armenian Christians, both of the Armenian Apostolic Church and of the Armenian Catholic Church, they use in their own language a term meaning "holy offering" or "holy sacrifice".
