Contradiction with Matthew 10:8
This verse instructs to "freely give" as one has received, implying not to accept support for preaching, contrasting the acceptance of support which Paul discusses.
Matthew 10:8: Heal the sick, cleanse the lepers, raise the dead, cast out devils: freely ye have received, freely give.
Contradiction with Acts 20:33-35
Paul states he coveted no one's silver or gold and worked with his own hands, seemingly contradicting the idea of accepting support.
Acts 20:33-35: I have coveted no man's silver, or gold, or apparel.
Contradiction with 2 Thessalonians 3:8-9
Paul emphasizes working to not be a burden, which contrasts with receiving support for the ministry.
2 Thessalonians 3:8-9: Neither did we eat any man's bread for nought; but wrought with labour and travail night and day, that we might not be chargeable to any of you:
Contradiction with Matthew 6:24
Jesus says one cannot serve God and money, suggesting a potential conflict with receiving monetary support.
Matthew 6:24: No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. Ye cannot serve God and mammon.
Paradox #1
The moral conflict in 1 Corinthians 9:12 could be seen in the balance between exercising personal rights and forgoing them for the benefit of others. Paul talks about giving up his right to receive support so as not to hinder the message, which might seem at odds with the principle of fairness and receiving what one is due. This raises questions about when it's right to insist on one's rights and when to sacrifice them for a greater good.
