On Days of Public Fasting
Samuel Rutherford 1642
The fast is indicted [called and set] eight days before, and the causes laid open for preparing of the people for humiliation (as Joel 2:1-3; Isa. 22:12,13). We have no anniversary [annual] and set fasts or feasts either, because God Himself by his judgment imminent, or already inflicted, or by permitting his people to follow their own ways, calls to fasting and mourning (Isa. 22:13, Joel 2:1-6, etc.), and so by his mercies and wonderful deliverances calls to extraordinary joy of thanksgiving (Ps. 118:24). The doctrine of the Law is preached (as Joel 2 and Isa 58), and the fast observed with abstinence from meat and drink, and carnal and ordinary pleasures (Joel 2:16).
