What distinguishes the Greek aorist tense from othersother past tenses is its denoting uninterrupted/non-continuing action: it is punctiliar, though the action in point of time can be lengthy, such as 'they fought against reacheach other'. 'Fought' in the aorist could be momentary or take years; but the action is singular and completed. The Greek perfect tense differs greatly from the aorist by including the idea that the result of the action abides. For example, "He is risen." Risen in the Greek perfect means He rose and remains risen. In the ancient Greek middle voice, the aorist adds the idea that the whoever took the action participated in the outcome.
