A us senator just went full theocracy

Well luckily what will happen in the fall is republicans will probably get the house and senate and that means there will be effectively a grid lock. Joe Biden will just veto anything they do and then if Joe Biden wants to do something they will say no. This is probably the best case scenerio right now. Nothing will get done so they cant screw anything up worse.

... especially the cult of wokeness!

I think that what you don't realize is that the quote you provided is Alexander Hamilton quoting something Sir William Blackstone said on Natural Law.

When you place the quote in context, the true meaning of the quote makes perfect sense, and it can be seen very clearly that the quote is not contrary to Separation of Church and State:

"This will of his Maker is called the law of nature. For as God, when He created matter, and endued it with a principle of mobility, established certain rules for the perpetual direction of that motion; so, when he created man, and endued him with free will to conduct himself in all parts of life, He laid down certain immutable laws of human nature, whereby that free will is in some degree regulated and restrained, and gave him also the faculty of reason to discover the purport of those laws.

Considering the Creator only a Being of infinite power, He was able unquestionably to have prescribed whatever laws He pleased to His creature, man, however unjust or severe. But as He is also a Being of infinite wisdom, He has laid down only such laws as were founded in those relations of justice, that existed in the nature of things antecedent to any positive precept. These are the eternal, immutable laws of good and evil, to which the Creator Himself in all his dispensations conforms; and which He has enabled human reason to discover, so far as they are necessary for the conduct of human actions. Such, among others, are these principles: that we should live honestly, should hurt nobody, and should render to everyone his due; to which three general precepts Justinian has reduced the whole doctrine of law. But if the discovery of these first principles of the law of nature depended only upon the due exertion of right reason, and could not otherwise be obtained than by a chain of metaphysical disquisitions, mankind would have wanted some inducement to have quickened their inquiries, and the greater part of the world would have rested content in mental indolence, and ignorance its inseparable companion. As, therefore, the Creator is a Being, not only of infinite power, and wisdom, but also of infinite goodness, He has been pleased so to contrive the constitution and frame of humanity, that we should want no other prompter than to inquire after and pursue the rule of right, but only our own self-love, that universal principle of action. For he has so intimately connected, so inseparably interwoven the laws of eternal justice with the happiness of each individual, that the latter cannot be attained but by observing the former; and, if the former be punctually obeyed, it cannot but induce the latter. In consequence of which mutual connection of justice and human felicity, He has not perplexed the law of nature with a multitude of abstracted rules and precepts, referring merely to the fitness or unfitness of things, as some have vainly surmised; but has graciously reduced the rule of obedience to this one paternal precept, 'that man should pursue his own true and substantial happiness.' This is the foundation of what we call ethics, or natural law. For the several articles into which it is branched in our systems, amount to no more than demonstrating, that his or that action tends to man's real happiness, and therefore very justly concluding that the performance of it is a part of the law of nature; or, on the other hand, that this or that action is destructive to man's real happiness, and therefore that the law of nature forbids it.

This law of nature, being coeval with mankind and dictated by God Himself, is of course superior in obligation to any other. It is binding over all the globe in all countries, and at all times: no human laws are of any validity, if contrary to this; and such of them as are valid derive all their force, and all their authority, mediately or immediately, from this original. But in order to apply this to the particular exigencies of each individual, it is still necessary to have recourse to human reason; whose office it is to discover, as was before observed, what the law of nature directs in every circumstance of life; by considering, what method will tend most effectually to our own substantial happiness. And if our reason were always, as in our first ancestor before his transgression, clear and perfect, unruffled by passions, unclouded by prejudice, unimpaired by disease or intemperance, the task would be pleasant and easy; we should need no other guide but this. But every man now finds the contrary in his own experience; that his reason is corrupt, and his understanding full of ignorance and error."

Don't get me wrong, I wish that the quote were contrary to Separation of Church and State, but it isn't. It is about Natural Law, which is the belief that all human beings have the ability to know what is good and what is evil through their intellect alone, and that no law or value contrary to Natural Law has any sort of merit whatsoever.
