Jesus only uses it twice, and it has a lot of different meanings depending on to what it is being applied. When applied to people, it means either "accomplished," or "the best of a kind." It could also mean "without spot or blemish," but that meaning is usually applied to sacrifices. It could also mean "complete" but that meaning is usually applied to numbers. It means something completely different when applied to God.
