For the Orthodox Christian the '''Lord's Day''' is the first day of the week. Often it is also called the eighth day in honor Our Lord's [[Resurrection]] and the new life he brought. In the English language, and other languages of Germanic origin, the day is called '''Sunday''' or some linguistic variation. In many languages around the Mediterranean Sea the name for this day is derived from ''Lord's Day'', while other languages including Slavic languages use a word derived from the word ''Resurrection''.
The practice of observing the Divine Liturgy on the first day of the week has its origin in Apostolic times. Then, the first day of the week was a day of special observance for the Christian community as it assembled to celebrate the breaking of the bread as indicated in Acts 20:7 and [[I Corinthians|I Cor]] 16:2. Later, the ''[[Didache]]'' of the first or second century gives the injunction: ''"On the Lord's Day come together and break bread. And give thanks, after confessing your sins that your sacrifice may be pure."'' The Christian writers St [[Justin Martyr]] and [[Tertullian]] of the third century mention assembling for worship on the first day of the week. By the fourth century the practice of the earlier times of setting aside first day of the week for assembly and rest began to be codified in both civil and church [[canon]]s and specifically for the Orthodox Church in the canons of the Council of Nicea.
