Contradiction with Exodus 20:3
This verse commands exclusive worship of God, whereas 1 Thessalonians 1:9 commends the Thessalonians for turning from idols to serve the living and true God, not necessarily contradicting but supporting monotheistic worship.
Exodus 20:3: Thou shalt have no other gods before me.
Contradiction with Isaiah 44:6
This verse affirms there is no God besides Yahweh, which aligns with 1 Thessalonians 1:9's view of idol rejection and exclusive worship of the true God.
Isaiah 44:6: Thus saith the LORD the King of Israel, and his redeemer the LORD of hosts; I [am] the first, and I [am] the last; and beside me [there is] no God.
Contradiction with 1 Corinthians 10:20-21
It warns against fellowship with demons through idol worship, resonating with 1 Thessalonians 1:9's turning from idols, reinforcing the message rather than contradicting it.
1 Corinthians 10:20-21: But I [say], that the things which the Gentiles sacrifice, they sacrifice to devils, and not to God: and I would not that ye should have fellowship with devils.
