St. Paul says [cf. Romans 13:11-14] - remaining awake and vigilant.
St. Chromatius of Aquileia wrote: "May the Lord remove such a danger from us so that we are never lulled into the sleep of infidelity; but may he grant his grace and his mercy so that we can always be vigilant in fidelity to him" [Sermon 32, 4]. JOHN PAUL II / BENEDICT XVI
