The laws of God are usually regarded as of two kinds—moral and positive. By a moral law, we are to understand a law which enjoins something in itself necessarily and eternally right, and which would be binding on God’s rational creatures, even though it had not been enjoined by an express commandment. Of this kind is the law which requires us to worship the true God only, to obey our parents, to abstain from murder, and many others which will readily occur to everyone. A positive law, on the other hand, is a law enjoining something which is not necessarily binding on men, and which becomes binding only in consequence of being commanded—such as the ceremonial observances which were imposed on the people of Israel, but which are no longer binding on the Church. For the reference, see Robert Gordon on the distinction between moral and positive laws.
