Righteous Father. He compares his disciples to the world, so as to describe more fully the approbation and favour which they had received from the Father; for it is proper that they who alone know God, whom the whole world rejects, should be distinguished above others, and most properly does Christ plead with peculiar warmth for those whom the unbelief of the world did not prevent from acknowledging God. By calling him Righteous Father, Christ defies the world and its malice; as if he had said, "However proudly the world may despise or reject God, still it takes nothing from him, and cannot hinder the honor of his righteousness from remaining unimpaired." By these words he declares that the faith of the godly ought to be founded on God, in such a manner that, though the whole world should oppose, it would never fail; just as, in the present day, we must charge the Pope with injustice, in order that we may vindicate for God the praise which is due to him. But I have known thee, and these have known that thou hast sent me. Christ does not merely say that God was known by the disciples, but mentions two steps; first, that he has known the Father; and, secondly, that the disciples have known that he was sent by the Father But as he adds immediately afterwards, that he has declared to them the name of the Father, he praises them, as I have said, for the knowledge of God, which separates them from the rest of the world. Yet we must attend to the order of faith, as it is here described. The Son came out of the bosom of the Father, and, properly speaking, he alone knows the Father; and, therefore, all who desire to approach God must betake themselves to Christ meeting them, and nmst devote themselves to him; and, after having been known by the disciples, he will, at length, raise them to God the Father.

Hath not known thee - See the notes at John 17:3.

The world hath not known thee - Has not acknowledged me. See on John 1:11, John 1:12 (note).
And these have known - Here our Lord, returning to the disciples, speaks:
1st. Of their having received him as the Messiah;
2dly. Of his making the Father known unto them;
3dly. Of his purpose to continue to influence them by the Spirit of truth, that they might be perfectly united to God, by an indwelling Savior for ever.

O righteous Father,.... God is righteous in all the divine persons: the Father is righteous, the Son is righteous, and the Holy Spirit is righteous: he is so in his nature; righteousness is a perfection of it; he is so in all his purposes and promises; in all his ways and works of providence and grace; in predestination, redemption, justification, pardon of sin, and eternal glory. Christ makes use of this epithet, as containing a reason why he might justly expect that all his petitions and claims, on behalf of himself and people, would be regarded:
the world hath not known thee; the unbelieving Jews, and idolatrous Gentiles, wicked men, one or another, know not God: as not the Father, so neither the Son, nor Spirit; though deity may be known by them, or that there is a God, yet they know not God in Christ, nor as the Father of Christ, or as their Father in him, nor what it is to have communion with him; nor do they know any of the things of God in a spiritual way; which shows the darkness and blindness of men by nature, the necessity of a divine illumination, and the miserable state of men without one:
but I have known thee; his nature, perfections and glory, his secret thoughts, purposes and designs, his covenant, promises and blessings, his love, grace and good will to his people, his whole mind and will; as he needs must, since he was one with him, and lay in his bosom;
and these have known that thou hast sent me; meaning his disciples and apostles, whom he distinguishes from the world; these knew the Father that sent him, and that he was sent by the Father; they knew the love of the Father in sending of him, the manner in which he was sent, and the end, man's redemption, for which he was sent; and acknowledged all this, and which laid them under an obligation to trust in him, love him, and magnify his grace; and is used by Christ as an argument with the Father to be concerned for them.

O righteous Father, the world hath not known thee--knew thee not.
but I have known thee--knew thee.
and these have known--knew.
that thou hast sent--sentest
me--As before He said "Holy Father," when desiring the display of that perfection on His disciples (John 17:11), so here He styles Him "Righteous Father," because He is appealing to His righteousness or justice, to make a distinction between those two diametrically opposite classes--"the world," on the one hand, which would not "know the Father, though brought so nigh to it in the Son of His love, and, on the other, Himself, who recognized and owned Him, and even His disciples, who owned His mission from the Father.

Righteous Father - The admission of believers to God through Christ, flows even from the justice of God.
