Contradiction with Matthew 5:39
Ephesians 6:17 refers to the "sword of the Spirit," suggesting a metaphorical readiness for spiritual battle, whereas Matthew 5:39 advocates for non-resistance to evil, emphasizing turning the other cheek instead of confrontation.
Matthew 5:39: But I say unto you, That ye resist not evil: but whosoever shall smite thee on thy right cheek, turn to him the other also.
Contradiction with Romans 12:19
Ephesians 6:17 highlights using God's word as a weapon against evil, while Romans 12:19 advises against taking vengeance, leaving judgment to God.
Romans 12:19: Dearly beloved, avenge not yourselves, but [rather] give place unto wrath: for it is written, Vengeance [is] mine; I will repay, saith the Lord.
Contradiction with Isaiah 2:4
Ephesians 6:17 uses the imagery of a sword, albeit spiritual, for combat against evil, but Isaiah 2:4 speaks of turning swords into plowshares and living peacefully without learning war.
Isaiah 2:4: And he shall judge among the nations, and shall rebuke many people: and they shall beat their swords into plowshares, and their spears into pruninghooks: nation shall not lift up sword against nation, neither shall they learn war any more. [pruninghooks: or, scythes]
Contradiction with John 18:36
Ephesians 6:17 speaks of engaging in spiritual warfare, but John 18:36 suggests Jesus’s kingdom is not of this world and refrains from earthly battles, indicating a contrast to literal or metaphorical combat.
John 18:36: Jesus answered, My kingdom is not of this world: if my kingdom were of this world, then would my servants fight, that I should not be delivered to the Jews: but now is my kingdom not from hence.
