Most of us have never heard one. It goes like this:
First, a central idea, which the group of readings contains, will be articulated. In this way, the homilist can illuminate the overall salvific meaning of the Lectionary readings.
Second, one doctrine from the Deposit of Faith or Catholic morals which the readings contain will be identified. The outline will help the homilist define, explain, and illustrate this doctrine.
Third, practical ways that the laity can apply this doctrine to their lives will be offered. This third step helps accomplish the Churchs desire that the homilist nurture the Christian life of the lay faithful. It helps fulfill the goal of the Year of Faith that the faith be lived.
It’s based on the idea of church as depositary (bigger than any of us), which is quite a major aspect, I’d say, giving pause to us who entertain even strenuous misgivings.
I may add the deposit of writings over the centuries, from earliest times. What the preacher quotes is what the people pray, or determines it, to adjust the ancient slogan, Lex orandi lex credendi, “The rule of prayer determines the rule of faith.”
Etc. Don’t get me started.
