On Method in Catholic Moral Theology My question is: what is a method (step-by-step recipe) in catholic moral theology? Optatam totius 16 provides the following guidelines for the dogmatic theology:


Biblical topics
Patristic reflections
Further evaluation of the topic
Speculation with Thomas Aquinas
Presence of mysteries in liturgy and life of church
Solution of people's problems
Adequate communication of results


For the moral theology, there is no list like that. We only read:


  Likewise let the other theological disciplines be renewed through a more living contact with the mystery of Christ and the history of salvation. Special care must be given to the perfecting of moral theology. Its scientific exposition, nourished more on the teaching of the Bible, should shed light on the loftiness of the calling of the faithful in Christ and the obligation that is theirs of bearing fruit in charity for the life of the world. 


I guess that there might be several alternative methods in moral theology to study a specific phenomenon. Perhaps, they might differ for studying a specific situation (e.g. what is a just reward for a specific work) and for analysis of abstract topics (e.g. to what extend is Reiki acceptable for catholics).

The accepted answer will provide a step-by-step way how to work in catholic moral theology, possibly justified and linked to some relevant documents.

Thank you for your help.
Teaching Catechism to 12-15 year olds for the last ten years has ingrained in me the Moral Decision Making Framework, which might be a little... Non-academic for the tone of this question, but it seems relevant to me.  You can see it applied in the Just War theory.  It boils down to his three things.


Circumstances
Object
Means


In consideration of some potentially sinful action you can judge the gravity of the sin (i.e. guilt) by considering those three things.

If i were to kill someone and the circumstances were that they were trying to kill me, i might be less guilty; if i were to kill someone i ran over accidentally, i might be less guilty because my object wasn't their death; and if i were to kill someone who was trying to kill me by rolling them over with a steam roller then i might be more guilty because those means are a tad excessive.

Most of this is spelled out and rooted in scripture in the Faith and Life series Our Life in the Church" the moral decision making framework is what the Bishops (around here at least) are having us teach as part of the settlement with the abuse victims.
