The disciple is not ... - The learner is not above his teacher, does not know more, and must expect to fare no better. This seems to have been spoken to show them that they were not to expect that their disciples would go "beyond them" in attainments; that if they were blind, their followers would be also; and that therefore it was important for them to understand fully the doctrines of the gospel, and not to be blind leaders of the blind.

Every one that is perfect - The word rendered "is perfect" means sometimes to repair or mend, and is thus applied to mending nets, Matthew 4:21; Mark 1:19. Hence, it means to repair or amend in a moral sense, or to make whole or complete. Here it means, evidently, "thoroughly instructed" or "informed." The Christian should be like his Master - holy, harmless, and undefiled, and separate from sinners. He should copy his example, and grow into the likeness of his Redeemer. Nor can any other be a Christian.

Every one that is perfect - Or, thoroughly instructed, κατηρτισμενος: - from καταρτιζω, to adjust, adapt, knit together, restore, or put in joint. The noun is used by the Greek medical writers to signify the reducing a luxated or disjointed limb. It sometimes signifies to repair or mend, and in this sense it is applied to broken nets, Matthew 4:21; Mark 1:19; but in this place, and in Hebrews 13:21; 2 Timothy 3:17, it means complete instruction and information. Every one who is thoroughly instructed in Divine things, who has his heart united to God, whose disordered tempers and passions are purified and restored to harmony and order; every one who has in him the mind that was in Christ, though he cannot be above, yet will be as, his teacher - holy, harmless, undefiled, and separate from sinners.

"The disciple who perfectly understands the rules and sees the example of his master, will think it his business to tread exactly in his steps, to do and suffer upon like occasions, as his master did: and so he will be like his master." Whitby.

The disciple is not above his master,.... Or "more excellent", as the Syriac, Arabic, and Persic versions render it; that is, in learning and knowledge; if the master is ignorant, the scholar will be so too; and thus it is with teachers, and their people under their care; if the leaders are blind and ignorant, those under their instructions will remain so likewise. These words are an illustration of the preceding parable, and are used to another purpose here than in Matthew 10:24. See Gill on Matthew 10:24.

but every one that is perfect shall be as his master. The Vulgate Latin reads it, "every one shall be perfect if he is as his master"; that is, if his master is a man of general learning, and a complete scholar, if he is like him, he will be so too: the Persic version renders it, "every disciple that desires perfection shall be as his master": whoever is ambitious of being a thorough scholar, and is diligent and industrious, by all ways and means, to obtain such a character, shall be even as good an one as his master, under whom he learns, and better he cannot well expect to be; and this is sufficient; and so the Ethiopic version renders it, "is it not enough that every one be as his master?" agreeably to Matthew 10:25

Maimonides (i) has an expression much like this:

"he that learns, shall not be greater than he of whom he learns, but shall be, "as he".''

Christ, in this last clause, seems to design his own disciples, who, when perfect in knowledge, which is not to be expected in this state, unless in a comparative sense, will be like himself.

Perfect (κατηρτισμένος)

Rev., rendering the participle more literally, perfected. See on Matthew 4:21. The word signifies to readjust, restore, set to rights, whether in a physical or a moral sense. See 1 Corinthians 1:10, where Paul exhorts to be perfectly joined together (κατηρτισμένοι) in opposition to being divided. In Galatians 6:1, it is used of restoring a brother taken in a fault. Hence the meaning to perfect, as Ephesians 4:12. Used in medical language of setting a bone or joint.

The disciple is not above his master: but every one that is perfect shall be as his master.

6:40 The disciple is not above his master. See PNT Mt 10:24.

6:40 Mt 10:24; John 15:20.

that...: or, shall be perfected as his master

40. The disciple, &c.-that is, "The disciple aims to come up to his master, and he thinks himself complete when he does so: if you then be blind leaders of the blind, the perfection of one's training under you will only land him the more certainly in one common ruin with yourselves."

6:37-49 All these sayings Christ often used; it was easy to apply them. We ought to be very careful when we blame others; for we need allowance ourselves. If we are of a giving and a forgiving spirit, we shall ourselves reap the benefit. Though full and exact returns are made in another world, not in this world, yet Providence does what should encourage us in doing good. Those who follow the multitude to do evil, follow in the broad way that leads to destruction. The tree is known by its fruits; may the word of Christ be so grafted in our hearts, that we may be fruitful in every good word and work. And what the mouth commonly speaks, generally agrees with what is most in the heart. Those only make sure work for their souls and eternity, and take the course that will profit in a trying time, who think, speak, and act according to the words of Christ. Those who take pains in religion, found their hope upon Christ, who is the Rock of Ages, and other foundation can no man lay. In death and judgment they are safe, being kept by the power of Christ through faith unto salvation, and they shall never perish.
