INTRODUCTION 1. DEFINITION.-Eschatology is the crown and capstone of dogmatic theology. It may be defined as "the doctrine of the last things," and tells how the creatures called into being and raised to the supernatural state by God, find their last end in Him, of whom, and by whom, and in whom, as Holy Scripture says, "are all things." Eschatology is anthropological and cosmological rather than theological; for, though it deals with God as the Consummator and Universal Judge, strictly speaking its subject is the created universe, i. e. man and the cosmos. The consummation of the world is not left to "fate" (fatum, ). God is a just judge, who distinguishes strictly between virtue and vice and metes out reward or punishment to every man according to his deserts. The rational creatures were made without their choice;but they cannot reach final end without their cooperation. Their destiny depends upon the attitude they take towards the divine plan of salvation. The good are eternally rewarded in Heaven, the wicked are punished forever in Hell. In the latter God will manifest His justice, while in the former He will show His love and mercy. By dealing justly with both good and bad, He at the same time triumphantly demonstrates His omnipotence, wisdom, and holiness. Thus Eschatology leads us back to the theological principle that the created universe in all its stages serves to glorify God. The consummation of the world may be regarded either as in process (in fieri) or as an accomplished fact (in facto esse). Regarding it from the former point of view we speak of the "last things" (novissima, ), i. e. the events to happen at the second coming of our Lord. "The four last things of man" are Death, Judgment, Heaven (Purgatory), and Hell. The four last things of the human race as a whole are: the Last Day, the Resurrection of the Flesh, and the Final Judgment, followed by the End of the World. These four events constitute so many stages on the way to the predestined state of consummation (consummatio saeculi, ), which will be permanent and irrevocable.
