So is all the church teaches and believes about natural law, since we need the church to reveal it infallible?
We don’t need the Church to “reveal” the natural law – it was understood very long ago. St Paul refers to a law “written on the heart” which informs the consciences of even the Gentiles who do not have the revealed law of Moses to guide them. (Rom 2:14-15).
The Roman philosopher Cicero (died 43 B.C.) wrote in* De Republica*, 3.22: “True law is right reason in agreement with nature. It is of universal application, unchanging, everlasting. We cannot be freed from it by Senate or people. This law is not one thing at Rome and another at Athens, but is eternal and immutable, valid for all nations and for all times. God is the Author of it, its promulgator, and its enforcing judge. Whoever is disobedient to it is abandoning his true self and denying his own nature.”
Roman jurist Domitius Ulpianus (c. 160 A.D. - 228 A.D.) had said, “by the law of nature all men are equal.”—Digest, L, 17.32; and “natural law regards all men as equal”—On Sabinus, Book XLIII.
The natural law means that if you want things to prosper, you have to use them in accord with their nature. If you want to grow good tomatoes, you have to treat tomato plants in accord with their nature. You have to give them sunshine and water and fertilizer and a good soil. It is something that man can discover by the basis of his own reason, if his understanding is not obscured by his culture – which happens to be in turmoil through relativism and selfism.

Address of Papal Theologian on Natural Moral Law
“The Moral Natural Law: Problems and Prospects,”
Rome, Feb. 24, 2007 (Zenit.org)
“There is a rapid decline of appreciation of basic moral truths and of the capacity of seeing what is obvious, in the name of that which is fleeting, ephemeral, and therefore not intrinsically binding. Will the social and political approval of gay marriages, of the adoption of children by gays and lesbians, of divorce, of contraception, abortion, euthanasia, the manipulation of embryos and laissez-faire theories of education finally arrive at the point of total absurdity, causing as a backlash a desperate return to rationality in ethics? We may certainly hope so in our wishful thinking, but for a few generations, the return to moral sanity may turn out to be too late.”
What is at stake is the essence of the law of nature or the natural moral law. The objective is to be able to answer all of the commonly held and promoted false opinions on abortion, homosexuality, euthanasia, IVF, stem cell research (SCR) and more, on the basis of human reason. Doctrine enables us to be infallibly certain of what reason upholds, for it is false reasoning and/or uncontrolled emotions and wills, which have produced so many terrible assaults on mankind since time began.
Once again we see that the principle that good ought to be done and evil avoided is written on the heart, and the papal theologian gives us the reason why, through the fudging of “obvious” morality by a wilful attention instead to the bizarre, this natural law is wilfully avoided. (So is faith by dissenters).
