(akatalutos (Heb 7:16), aperantos (1Ti 1:4)):
This English word occurs twice in the [[New Testament]], and is there represented by the two Greek words above noted.
(1) In Heb 7:16 Jesus is said to be a priest "after the power of an endless life." The word means literally, as in the [[Revised Version]], margin, "indissoluble." It is not simply that Christ’s priesthood was eternal. The priesthood was based upon His possession, by nature, of a life which in time and eternity death could not touch. This distinguished Him essentially from priests under the law.
(2) In 1Ti 1:4, Paul warns Timothy against giving heed in his ministry to "fables (muthoi) and endless (limitless) genealogies." The allusion seems to be to the series of emanations (aeons) in Gnostic speculation, to which no limit could be set.
Distinct from the above are the words denoting "everlasting," "eternal," which see.
