He is now treating of the last judgment, when Christ shall come from heaven to judge the quick and dead. This day of the Divine judgment we call the Last Day, that is, the end of time; for we cannot tell through how many days that judgment will be prolonged; but day, as is the use of holy Scripture, is put for time. And we therefore call it the last or latest judgment, because He both now judges and has judged from the beginning of the human race, when He thrust forth the first man from the tree of life, and spared not the Angels that sinned. But in that final judgment both men and Angels shall be judged together, when the Divine power shall bring each man’s good and evil deeds in review before his memory, and one intuitive glance shall present them to the perception, so that at once we shall be condemned or acquitted in our consciences.
