Adventus – the ancient Romans used that word to denote a solemn welcome ceremony for the emperor arriving at a city; usually the city was caput orbis terrarum, i.e. Rome. Since the time of the Dominate the emperors, as the rulers of the world, started to address themselves as dominus et deus.
We’ve begun the period of Advent – the time of preparations to welcome the true God and Emperor of the World. We will meditate the mystery of his humble Incarnation, remembering, however, the promise he gave us: our Lord and God shall come again, this time in glory wand power, as King of kings and Lord of the lords.
