Infidel
Morrish Bible Dictionary [1]
The Greek word is ἄπιστος, 'not believing,' and hence an 'unbeliever.' 2 Corinthians 6:15; 1 Timothy 5:8 . The word is translated 'unbeliever' in Luke 12:46; 1 Corinthians 6:6; 1 Corinthians 14:23; 2 Corinthians 6:14; and 'unbelieving' in 1 Corinthians 7:14,15; Titus 1:15; Revelation 21:8 . Thus the scriptural use of the term does not imply the denial of the truth of Christianity, as it is now commonly understood.
Webster's Dictionary [2]
(1): ( n.) One who does not believe in the prevailing religious faith; especially, one who does not believe in the divine origin and authority of Christianity; a Mohammedan; a heathen; a freethinker.
(2): ( a.) Not holding the faith; - applied esp. to one who does not believe in the inspiration of the Scriptures, and the supernatural origin of Christianity.
Hastings' Dictionary of the Bible [3]
Infidel . This word has more force now than formerly. In AV [Note: Authorized Version.] it signifies no more than ‘unbeliever.’ It occurs in 2 Corinthians 6:15 , 1 Timothy 5:8 (RV [Note: Revised Version.] ‘unbeliever’ in both). So ‘infidelity’ in 2Es 7:44 is simply ‘unbelief’ (Lat. incredulitas ).
King James Dictionary [4]
IN'FIDEL, a. L. infidelis in and fidelis faithful.
Unbelieving disbelieving the inspiration of the Scriptures, or the divine institution of christianity.
The infidel writer is a great enemy to society.
IN'FIDEL, n. One who disbelieves the inspiration of the Scriptures, and the divine origin of christianity.
International Standard Bible Encyclopedia [5]
in´fi - del ( ἂπιστος , ápistos , "unbelieving," "incredulous"): the King James Version has this word twice: "What part hath he that believeth with an infidel?" ( 2 Corinthians 6:15 ); "If any provide not for his own,... is worse than an infidel" ( 1 Timothy 5:8 ). In both passages the English Revised Version and the American Standard Revised Version have "unbeliever" in harmony with numerous other instances of the use of the Greek apistos ̌ . The word nowhere corresponds to the modern conception of an infidel, one who denies the existence of God, or repudiates the Christian faith; but always signifies one who has not become a believer in Christ. It was formerly so used in English, and some of the older versions have it in other passages, besides these two. It is not found in the Old Testament, but "infidelity" (incredulity) occurs in 2 Esdras 7:44 (114).
