Contradiction with Exodus 20:3
Romans 14:11 acknowledges God as Lord, but Exodus 20:3 is part of the Ten Commandments, emphasizing the worship of God alone, which can be seen as not acknowledging all knees bowing universally, including to other understandings of divinity in various contexts.
Exodus 20:3: Thou shalt have no other gods before me.
Contradiction with Psalm 10:4
Romans 14:11 declares every knee shall bow to God, but Psalm 10:4 implies that the wicked, in their pride, do not seek God or acknowledge Him, contradicting the universal submission described.
Psalm 10:4: The wicked, through the pride of his countenance, will not seek [after God]: God [is] not in all his thoughts. [God is...: or, all his thoughts are, There is no God]
