And there were present, at that very time, some that told him of the Galileans, whose blood Pilate had mingled with their sacrifices. And he answering, said to them: Think you that these Galileans were sinners above all the men of Galilee, because they suffered such things? No, I say to you: but unless you shall do penance, you shall all likewise perish. Or those eighteen upon whom the tower fell in Siloe, and slew them: think you, that they also were debtors above all the men that dwelt in Jerusalem? No, I say to you; but except you do penance, you shall all likewise perish.
— St Luke xiii, 1-5
Our Lord here teaches the moral we mortal men ought draw from every disaster, man-made or natural: those who died in the fall of the tower at Siloe, those who perished in the collapse of the spire in Christchurch, they were no worse nor better than we are; "but except you do penance, you shall all likewise perish." Thus saith the Lord!
On Occasion of an Earthquake.
O LORD our God, We desire with the utmost Reverence to prostrate our Souls before Thee, confessing that Thou art a great God, mighty and terrible; Thou removest the Mountains, and overturnest them in thine Anger, Thou shakest the Earth out of her Place, and makest the Pillars thereof to tremble. We beseech Thee, O Lord, to awaken our Attention, duly to consider and hear the Voice of thy amazing Judgements, and to learn the Instructions they have a tendency to convey: may We every one of us examine our own Hearts, see where we have done Iniquity, and sincerely resolve to do so no more: Suffer us not, as soon as our present Consternation is over, to forget our Deliverance, or to grow vain and presumptuous, lest a worse Thing should befall us. We acknowledge it is of thy Goodness, O God, that we were not utterly consumed, and that we were not swallowed up quick, by the late dreadful Earthquake. O may a Sense of thy many wonderful Preservations of us continually abide upon our Hearts, and produce such a godly Care and Watchfulness in our Conduct, that, no Disaster in Life may ever surprize us; that Death itself, at what time and in what manner soever it cometh, may not find us unprepared; and that at length We may safely arrive at that Kingdom, which can never be moved; for the Sake of thy Mercy in Christ Jesus, our Worthy Mediator and Redeemer. Amen.
