Advent
Advent (Latin adventus, arrival or coming) designates in Christian theology the two comings of Christ: his first advent in the incarnation (the historical event of his birth, life, death, and resurrection) and his second advent at the end of the age (his visible, glorious return in judgment and salvation). As a liturgical season, Advent is the four-week period of preparation preceding Christmas in the Western church, observed since at least the 4th–5th centuries, combining penitential reflection on human need with joyful anticipation of Christ's coming. The dual focus of Advent — on the first coming already accomplished and the second coming yet awaited — is theologically rich: Christians live between the advents, in the "already/not yet" tension of the kingdom. The OT prophets spoke of the coming of the LORD in both immediate-historical and eschatological senses (Isa. 9:6; 40:3; Mal. 3:1), with NT retrospection seeing the first advent as fulfillment and the second as the remaining goal. The Advent season's scriptural themes include John the Baptist's preparation ministry (Matt. 3:1–3; Isa. 40:3), Mary's Magnificat (Luke 1:46–55), the messianic promises (Isa. 7:14; 9:1–7; 11:1–9), and eschatological readiness (Matt. 24:42–44; Rom. 13:11–14). The theological center of Advent is Christ himself — Emmanuel, God with us — who came, who comes in Word and Spirit, and who will come again.
