Pure religion and undefiled before God and the Father is this, To visit the fatherless and widows in their affliction…
The figure is doubtless derived from the Jewish law; the touch of the ceremonially defiled, of a grave, a carcase, a bone, or an unclean animal, imparted pollution to a man, and he had to submit to a cleansing process before he could join in the temple services or associate with his brethren. The world is graphically pictured as a graveyard, leper-house, a den of unclean beasts, through which the believer must pick his way so carefully and circumspectly that he may escape contact with the all-surrounding corruptions, and come forth with his purity unsullied and unstained.
(F. T. Bassett, M. A.)
