PERFECT
The main words in the NT that receive this translation are “teleioõ”, “teleios”, “full, complete, perfect.”
The Lord Jesus was always morally perfect, and yet in the Scriptures we are told that He was “perfected,” for example, as the “author of salvation”: antitype of Joshua, leader in God’s purposes. Everything that had to do with this office was fulfilled (Heb. 2:10).
Although he was a Son, he nevertheless learned obedience (not “to be obedient”) by what he suffered; and having been “made perfect” (that is, glorified) after having accomplished the work of redemption, he became the author of eternal salvation to all who obey him (Heb. 5:9); This may be the meaning of the words “and on the third day I am perfected” (Lk. 13:32, literal Greek; cf. F. Lacueva: “New Interlinear Testament”, loc. cit., and the note he gives to the foot).
The disciples were exhorted to be perfect as His Father in heaven is perfect, for He gives His blessings to the evil and the good (Matt. 5:48). Through an offering Christ has perfected those who are sanctified forever.
His work consecrates them to the priesthood (Heb. 10:14; cf. Col. 1:12 and 1 Pet. 2:9). Being “perfect” is also applied to reaching “the measure of the stature of the fullness of Christ” (Eph. 4:13). The spirits of the righteous are made perfect (Heb. 12:23).
Paul had not yet been perfected (Phil. 3:12), yet he adds in verse 15, “Let all of us who are perfect feel the same way.”
There are several applications of the term that can be deduced from the context of each passage, but in general it can be said that it refers either to the purification of conscience, which is indispensable for the service of God, or to the perception of a true standard. (dead and resurrected with Christ) as a necessity of testimony for Christ here on earth.
