James 1:8 - Clarke's commentary and critical notes on the Bible

A double minded man is unstable in all his ways. A double-minded man - Ανηρ διψυχος· The man of two souls, who has one for earth, and another for heaven; who wishes to secure both worlds; he will not give up earth, and he is loth to let heaven go. This was a usual term among the Jews, to express the man who attempted to worship God, and yet retained the love of the creature. Rabbi Tanchum, fol. 84, on Deuteronomy 26:17, said: "Behold, the Scripture exhorts the Israelites, and tells them when they pray, לא יהיה להם שתי לבבות lo yiyeh lahem shetey lebaboth, that they should not have two hearts, one for the holy blessed God, and one for something else." A man of this character is continually distracted; he will neither let earth nor heaven go, and yet he can have but one. Perhaps St. James refers to those Jews who were endeavoring to incorporate the law with the Gospel, who were divided in their minds and affections, not willing to give up the Levitical rites, and yet unwilling to renounce the Gospel. Such persons could make no progress in Divine things.
