The aorist tense is characterized by its emphasis on punctiliar action; that is, the concept of the verb is considered without regard for past, present, or future time. There is no direct or clear English equivalent for this tense, though it is generally rendered as a simple past tense in most translations.
The events described by the aorist tense are classified into a number of categories by grammarians. The most common of these include a view of the action as having begun from a certain point ("inceptive aorist"), or having ended at a certain point ("cumulative aorist"), or merely existing at a certain point ("punctiliar aorist"). The categorization of other cases can be found in Greek reference grammars.
The English reader need not concern himself with most of these finer points concerning the aorist tense, since in most cases they cannot be rendered accurately in English translation, being fine points of Greek exegesis only. The common practice of rendering an aorist by a simple English past tense should suffice in most cases.
The passive voice represents the subject as being the recipient of the action. E.g., in the sentence, "The boy was hit by the ball," the boy receives the action.
The imperative mood corresponds to the English imperative, and expresses a command to the hearer to perform a certain action by the order and authority of the one commanding. Thus, Jesus' phrase, "Repent ye, and believe the gospel" (Mk.1:15) is not at all an "invitation," but an absolute command requiring full obedience on the part of all hearers.
