Contradiction with Matthew 12:50
It supports rather than contradicts Luke 8:21 by emphasizing obedience to God's will as defining family.
Matthew 12:50: For whosoever shall do the will of my Father which is in heaven, the same is my brother, and sister, and mother.
Contradiction with James 2:17
Contradicts by highlighting faith without works as dead, whereas Luke 8:21 emphasizes hearing and doing the word.
James 2:17: Even so faith, if it hath not works, is dead, being alone. [alone: Gr. by itself]
Contradiction with Romans 3:28
Suggests justification by faith without deeds, in contrast to Luke 8:21 which implies action by doing.
Romans 3:28: Therefore we conclude that a man is justified by faith without the deeds of the law.
Contradiction with Galatians 2:16
Emphasizes faith over the law for justification, whereas Luke 8:21 focuses on doing God’s word.
Galatians 2:16: Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified.
Contradiction with Romans 10:9
Highlights confession and belief for salvation, which contrasts with the doing aspect in Luke 8:21.
Romans 10:9: That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
Paradox #1
The contradiction might be that the verse could be seen as prioritizing spiritual relationships over biological family ties, which might conflict with the idea of honoring and valuing family. This could be seen as inconsistent with teachings that emphasize the importance of family bonds.
