1:26,27 When men take more pains to seem religious than really to be so, it is a sign their religion is in vain. The not bridling the tongue, readiness to speak of the faults of others, or to lessen their wisdom and piety, are signs of a vain religion. The man who has a slandering tongue, cannot have a truly humble, gracious heart. False religious may be known by their impurity and uncharitableness. True religion teaches us to do every thing as in the presence of God. An unspotted life must go with unfeigned love and charity. Our true religion is equal to the measure in which these things have place in our hearts and conduct. And let us remember, that nothing avails in Christ Jesus, but faith that worketh by love, purifies the heart, subdues carnal lusts, and obeys God's commands.
27. Pure … and undefiled—"Pure" is that love which has in it no foreign admixture, as self-deceit and hypocrisy. "Undefiled" is the means of its being "pure" [Tittmann]. "Pure" expresses the positive, "undefiled" the negative side of religious service; just as visiting the fatherless and widow is the active, keeping himself unspotted from the world, the passive side of religious duty. This is the nobler shape that our religious exercises take, instead of the ceremonial offices of the law.
before God and the Father—literally, "before Him who is (our) God and Father." God is so called to imply that if we would be like our Father, it is not by fasting, &c., for He does none of these things, but in being "merciful as our Father is merciful" [Chrysostom].
visit—in sympathy and kind offices to alleviate their distresses.
the fatherless—whose "Father" is God (Ps 68:5); peculiarly helpless.
and—not in the Greek; so close is the connection between active works of mercy to others, and the maintenance of personal unworldliness of spirit, word, and deed; no copula therefore is needed. Religion in its rise interests us about ourselves in its progress, about our fellow creatures: in its highest stage, about the honor of God.
keep himself—with jealous watchfulness, at the same time praying and depending on God as alone able to keep us (Joh 17:15; Jude 24).
