SUPEREROGATION, in theology, what a man does beyond his duty, or more than he was commanded to do. The Romanists stand up strenuously for works of supererogation, and maintain that the observance of evangelical councils is such. By means hereof, a stock of merit is laid up, which the church has the disposal of, and which she distributes in indulgences to such as need. The reformed church do not allow of any work of supererogation.
