Bible clearly says to obey local authorities unless what they're requiring is unBiblical.
Allowing those local authorities to suppress the preaching of the Gospel, particularly when they defy their own higher authorities and violate their sworn oaths of office by doing so, is unBiblical.
This is the oath anyone applying for a place on the ballot for a local election takes in Texas:
Before me, the undersigned authority, on this day personally appeared (name) _________________________________________, who being by me
here and now duly sworn, upon oath says: “I, (name)________________________________________, of _____________________________
County, Texas, being a candidate for the office of ______________________________________________________, swear that I will support and
defend the Constitution and laws of the United States and of the State of Texas. I am a citizen of the United States eligible to hold such office under
the Constitution and laws of this state. I have not been finally convicted of a felony for which I have not been pardoned or had my full rights of
citizenship restored by other official action. I have not been determined by a final judgment of a court exercising probate jurisdiction to be totally
mentally incapacitated or partially mentally incapacitated without the right to vote. I am aware of the nepotism law, Chapter 573, Government Code.
Texas Constitution, Article 1 Section 6:
FREEDOM OF WORSHIP. All men have a natural and indefeasible right to worship Almighty God according to the dictates of their own consciences. No man shall be compelled to attend, erect or support any place of worship, or to maintain any ministry against his consent. No human authority ought, in any case whatever, to control or interfere with the rights of conscience in matters of religion, and no preference shall ever be given by law to any religious society or mode of worship. But it shall be the duty of the Legislature to pass such laws as may be necessary to protect equally every religious denomination in the peaceable enjoyment of its own mode of public worship.
Section 8:
FREEDOM OF SPEECH AND PRESS; LIBEL. Every person shall be at liberty to speak, write or publish his opinions on any subject, being responsible for the abuse of that privilege; and no law shall ever be passed curtailing the liberty of speech or of the press. In prosecutions for the publication of papers, investigating the conduct of officers, or men in public capacity, or when the matter published is proper for public information, the truth thereof may be given in evidence. And in all indictments for libels, the jury shall have the right to determine the law and the facts, under the direction of the court, as in other cases.
Section 9:
SEARCHES AND SEIZURES. The people shall be secure in their persons, houses, papers and possessions, from all unreasonable seizures or searches, and no warrant to search any place, or to seize any person or thing, shall issue without describing them as near as may be, nor without probable cause, supported by oath or affirmation.
One can easily argue that a city that issues mass subpoenas for sermons implies an intent to take legal action, and fully intends their actions to have a chilling effect on the freedom of speech of churches.
