Contradiction with Matthew 5:17
This verse suggests that Jesus came to fulfill the law, not abolish it, which could contradict practices from the law, like the Feast of Tabernacles.
Matthew 5:17: Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
Contradiction with Colossians 2:16
This verse implies that believers should not be judged on whether they observe festivals, which contrasts with the observance in Ezra 3:4.
Colossians 2:16: Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath [days]: [in meat...: or, for eating and drinking] [respect: or, part]
Contradiction with Galatians 4:9-10
These verses suggest returning to observing special days could be seen as a regression, which contradicts the reinstatement of such a festival in Ezra 3:4.
Galatians 4:9-10: But now, after that ye have known God, or rather are known of God, how turn ye again to the weak and beggarly elements, whereunto ye desire again to be in bondage? [turn ye again: or, turn ye back] [elements: or, rudiments]
Contradiction with Hebrews 10:1
This verse states the law is only a shadow of good things to come, possibly conflicting with the detailed observance of feasts like in Ezra 3:4.
Hebrews 10:1: For the law having a shadow of good things to come, [and] not the very image of the things, can never with those sacrifices which they offered year by year continually make the comers thereunto perfect.
Paradox #1
Ezra 3:4 describes following specific religious rituals and practices. Some might see a moral conflict in the rigid adherence to rituals while others might stress that true morality should focus on ethical behavior and personal faith rather than on strict ceremonial observance.
