When Church teaching is publicly attacked, it must be publicly defended.
Mt 10:27
It was no longer a private matter the moment the complainer went to the press.
The verse cited does not support your proposition of defending the roman regulation.
This is the message at issue in that verse is this:
7As you go, preach this message: ‘The kingdom of heaven is near.’ 8Heal the sick, raise the dead, cleanse those who have leprosy,[b]drive out demons. Freely you have received, freely give.

Please again note, I have zero against the RCC or RCs.
It’s a fine denomination.
I do respectfully think that the RCC, like all denominations are wont to do (Baptists with their dunking and no drinking comes to mind), add well-meaning, but ultimately misquided, rules and regulations to the Gospel.
