Do not the lessons of earthquakes and similar disasters prove such belief in guardian angels to be humbug?

The Catholic Answers

No. Angels are not supposed to stop earthquakes. They co-operate in the work of our salvation, inspiring good thoughts, and making us uneasy when temptations suggest themselves. I do not disbelieve in angels because they do not do what they are not supposed to do. A guardian angel could, were it God’s will, prevent temporal calamities, but that is not ordinary, and is not ordinarily to be expected. Temporal and natural events depend upon temporal and natural causes. Nor do temporal calamities really matter. It is the supernatural life of the soul that really counts. It is enough to remark that God has appointed certain supernatural means for our supernatural safety, and amongst those means are guardian angels.
