Matthew Henry on James 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.
