Martin Luther on Excommunication.
The greatest punishment God can afflict on the wicked, is when the church, to chastise them, delivers them over to Satan, who, with God's permission, kills them, or makes them undergo great calamities. Many devils are in woods, in waters, in wildernesses, and in dark pooly places, ready to hurt and prejudice people; some are also in the thick black clouds, which cause hail, lightnings, and thunderings, and poison the air, the pastures and grounds. When these things happen, the philosophers and physicians say, it is natural, ascribing it to the planets, and showing I know not what reasons for such misfortunes and plagues as ensue.
