The principal words in the N.T. thus translated are ???????, ???????, 'full, complete, perfect.' The Lord Jesus was always morally perfect, yet scripture speaks of His being 'made perfect,' for instance, as the captain of salvation: antitype of Joshua, leader into the purpose of God. All had been completed in view of that office. Heb 2:10. Though a Son, yet He learned obedience (not 'to be obedient') by the things which He suffered; and being made 'perfect ' (that is, glorified) after He had finished the work of redemption, He became the author of eternal salvation to all that obey Him (Heb 5:9): this may be the meaning of the words "the third day I shall be perfected." Lu 13:32.
The disciples were exhorted to be perfect as their Father in heaven is perfect, for He sends His blessings on the evil and the good. Mt 5:48. By one offering Christ hath perfected for ever them that are sanctified. His work consecrates them for the priesthood, Heb 10:14: cf. Col 1:12. Being 'perfect' is also applied to being a 'full grown ' man. Eph 4:13. The same word is translated 'of full age' in Heb 5:14; and simply 'men' (of a ripe age) in 1Co 14:20. The spirits of just men are made perfect. Heb 12:23. Paul was not yet perfected, Php 3:12; yet in Php 3:15 he adds "as many as be perfect be thus minded." There are various applications of the term which can be gathered from the context of each occurrence, but in general it may be said to have reference either to the purging of conscience, which is indispensable to the service of God, or to intelligence of a true standard (dead and risen with Christ) as a necessity to testimony for Christ here.
