Contradiction with Proverbs 4:23
This verse advises to keep the heart with all diligence, which contradicts Luke 14:34's mention of salt losing its savor, emphasizing maintenance and vigilance rather than loss and deterioration.
Proverbs 4:23: Keep thy heart with all diligence; for out of it [are] the issues of life. [with...: Heb. above all keeping]
Contradiction with Matthew 5:13
It suggests that if salt loses its savor, it is good for nothing, which can be seen as consistent with Luke 14:34, but the underlying implication in Matthew of permanence once one is a disciple could be seen in contrast to Luke's warning about losing flavor.
Matthew 5:13: Ye are the salt of the earth: but if the salt have lost his savour, wherewith shall it be salted? it is thenceforth good for nothing, but to be cast out, and to be trodden under foot of men.
Contradiction with Mark 9:50
It emphasizes being at peace with one another, which might seem contradicting if peace is lost due to salt losing its savor as suggested in Luke 14:34, focusing instead on restoration and unity.
Mark 9:50: Salt [is] good: but if the salt have lost his saltness, wherewith will ye season it? Have salt in yourselves, and have peace one with another.
Contradiction with Hebrews 10:39
It speaks about not being of those who shrink back and are destroyed, implying a steadfastness that contradicts the idea of losing flavor or purpose as warned in Luke 14:34.
Hebrews 10:39: But we are not of them who draw back unto perdition; but of them that believe to the saving of the soul.
