Columbanus was a holy pilgrim, a great pilgrim; it was first and foremost having traveled mostly 5,000 kilometers on foot, but it was no less so in his disposition of spirit and interior attitude. Colombano intended to realize in his life, taking it to its extreme consequences, that idea dear to Christian thought, which sees life as a journey or a pilgrimage on this earth to reach the true homeland, which is not of this world. It is an idea that he promptly expresses, often returning to it in his writings: “Wayfarers always ardently desire the end of their journey, so we too, who are wayfarers and pilgrims in this world, must think incessantly about the goal of the journey, that is, of our life: the end of our journey is our homeland.”
Hence another recurring idea, that of the transience of earthly life, of its brevity and fleetingness, on which Colombano uses a simile that testifies to his way of thinking as a true pilgrim: human life is short – he observes – “like a journey of a single day,” i.e., like a day’s journey: which is precisely the unit of measurement – time and space – usually used by faithful pilgrims.
