Human persons are incredible beings. We are called to love as God loves and to express love in and through our bodies. Love is a choice—i.e., a will-act, founded on the truth known by the mind, of at least two persons to give themselves to one another. It is absolutely necessary for the spiritual faculties of mind and will to “orchestrate” our various bodily capacities—e.g., emotions, so that we can express love in and through our bodies.
Often, this “orchestration” of the bodily powers does not succeed. “I do not understand my own actions. For I do not do what I want, but I do the very thing I hate” (Rom 7:15). If we have a favorite food—e.g., chocolate, we might decide not to eat more than a certain amount. Yet, in the end, almost to our own amazement, we often find that we have eaten more than we had planned. In this case, our bodies do not express the proper love of self. In our dealings with others, we sometimes make a firm resolution that we will not allow others to anger us. Yet we find ourselves becoming angry. In this case, our bodies do not express the proper love for others. The choices we make in our wills founded on the truths we know are not always carried out. Rather, we alter and change them.
