“Mores” (the plural of mos), are the group of standards or norms that determine right and wrong. It was first used by Cicero (De Fato, II.i) to translate the Greek ethikos. “Moral” means “according to the mores.”
When used of human societies this is a subjective groups of norms, pertinent to the group or culture from which they spring. When used by Christians it refers to the character of God as the norm or standard which determines what is good and right.
Moral law then, is law that springs from the unchanging nature of God as the norm by which good or evil is determined. That which accords with the character of God is good and right. That which is out of sync with the character of God is evil or wrong.
Liberty is not freedom from rules but the right to live according to the law and free from tyranny, which rides roughshod over the law.
Moral law provides the structure of freedom. Liberty is living freely within that structure.
“Human beings are by nature actors, who cannot become something until first they have pretended to be it. They are therefore not to be divided into the hypocritical and the sincere, but into the sane, who know they are acting, and the mad who do not.” -W.H. Auden
The process of transformation is not exclusively, or even primarily, interior nor exterior; rather, it is intentionally a tapestry of life’s aspects. Liturgy is a storied framework into which we enter and discover ourselves participants in a grand narrative. According to God’s design it is word-comprised, action-oriented, imagination-stimulating, and imagination-requisite.
We have been indwelt by the Holy Spirit but not habituated to Christ’s character; that is a process of taking thoughts and behaviors captive as we find ourselves increasingly within the story we were at first only rehearsing (Auden says “pretending”). Then captured by, formed by, and eventually inhabiting and inhabited by.
