Contradiction with Matthew 6:7
This verse advises against using vain repetitions in prayer, which contradicts the extended prayer and fasting for casting out demons indicated by Matthew 17:21.
Matthew 6:7: But when ye pray, use not vain repetitions, as the heathen [do]: for they think that they shall be heard for their much speaking.
Contradiction with James 2:17
This verse emphasizes faith without works is dead, suggesting action over prayer and fasting alone, which contradicts the emphasis on prayer and fasting in Matthew 17:21.
James 2:17: Even so faith, if it hath not works, is dead, being alone. [alone: Gr. by itself]
Paradox #1
Some contradictions or inconsistencies related to Matthew 17:21 arise because this verse is not found in many of the earliest manuscripts of the Bible. It's included in some versions, like the King James Version, but omitted in others, such as the NIV. This difference suggests it might have been added later by scribes, leading to debates about its authenticity and whether it reflects the original teachings.
